Cholescintigraphy in the diagnosis of acute cholecystitis.

Technetium-99-m-diethyl-IDA (Solco HIDA) cholescintigraphy was performed on 50 patients with suspected acute cholecysitis. The final diagnosis was acute cholecytitis in 34 cases, other biliary tract disease in 5 cases and nonbiliary disease in 11 cases. A nonfilling gallbladder was regarded as indicative of acute cholecystitis. The sensitivity in detecting acute cholecystitis was about 90%, the specificity about 80%; the predictive value of a positive test was about 90% and that of a negative test about 80%. The false positives consisted of two cases of acute pancreatitis with normal gallbladders and one case of coincidental chronic gallbladder disease and duodenal ulcer. The false negatives were examined after one week's treatment. A severe common bile duct obstruction could be detected in cholescintigraphy, but a slight obstruction was not always distinguishable from conditions in which the bile flow was normal.

Intravenous cholangiography and cholescintigraphy in the diagnosis of hepatobiliary disease.

The diagnostic yields of intravenous cholangiography (IVC) and 99mTc-diethyl-IDA cholescintigraphy (CS) were compared in 50 patients; 19 had acute cholecystitis, 5 pancreatitis, 4 obstructive disease of the common bile duct, 5 chronic gallbladder disease, 6 parenchymal liver disease and 11 had other intra-abdominal diseases. The comparison of IVC and CS covered three aspects: the definition of the biliary tract structures, their morphologic changes and an assessment of bile flow through the cystic duct and the common bile duct. The definition of the main intrahepatic bile ducts was better with IVC; that of the common bile duct and the gallbladder was better with CS. Morphologic details such as calculi or local changes in duct calibre were detected only in IVC. Measurements of common bile duct calibre obtained from operative cholangiograms correlated better with those from the IVCs than with those from the CSs. CS was more sensitive in the diagnosis of cystic duct obstruction. Bile flow in the common bile duct was estimated in the cases where the gallbladder did not fill. Delayed emptying of the common bile duct was revealed in IVC in 1 and in CS in 3 out of 6 cases with disturbed bile flow. The morphologic findings in IVC gave indication of the obstructive condition in the 1 case with retarded flow and in 2 additional cases. CS provided functional information for which the concentration of the tracer was sufficient except in one case. IVC provided morphologic and functional information, but the excretion of the contrast medium was insufficient for a morphologic assessment of the common bile duct in 16 cases and for a functional assessment in 11 cases.

Lymphographic diagnosis of malignant lymphoma in the course of Sjögren's syndrome.

Three patients with Sjögren's syndrome complicated by malignant lymphoma are presented. During the benign stage, two showed non-specific hyperplastic lymph node patterns on lymphography. When the disease had become malignant, all cases revealed generalized involvement of the retroperitoneal lymph nodes. The lymphographic pattern was that of a malignant lymphoma: enlarged nodes, with a foamy, linear or reticular appearance but mostly preserved marginal sinuses. On lymphographic follow-up, the node alterations were consistent with the histological findings and the clinical status, including the therapeutic response.

Lymphography in the assessment of mycosis fungoides.

Extracutaneous manifestations of mycosis fungoides imply a bad prognosis and are a major cause of death. Benign dermatopathic lymphadenopathy is associated with mycosis fungoides and often precedes lymphomatous infiltration. In this study, 10 patients in the early stages of mycosis fungoides underwent clinical and lymphographical examinations. In one the lymphoma was already present in lymph nodes. Six had signs of dermatopathic adenopathy which was verified by lymph node biopsy in 5. In one of these the disease later progressed to a malignant lymphoma. The frequent occurrence of lymph node involvement justifies the use of lymphography collaterally with staging laparotomy to determine the presence of pathologic retroperitoneal lymph nodes.

Double contrast X-ray examination of stomach.

A comparison was made between three double contrast methods and the conventional method of X-ray examination of the stomach. 106 patets received ordinary barium sulphate together with effervescent granules. 119 patients were examined with a special barium sulphate preparation containing dissolved carbon dioxide (Baritop). The third group, 100 patients, received Baritop and effervescent granules, and 100 patients a conventional barium meal. The films were analyzed as to the quality of mucosal pattern demonstration, mucosal affinity of the contrast medium, and the degree of dilatation of the stomach and duo8num. In addition, the degree of interference by gas bubbles was estimated. The best results were obtained with the contrast medium containing carbon dioxide (Baritop).

Tumor detection in extremities of man with 99mTc-tetracycline.

Twelve patients with tumors and three with osteitis of the extremities were studied using 99mTc-labelled tetracycline in order to image the process with gamma camera. The diagnosis of all cases were verified histologically. The labelled tetracycline was found to give positive images for the most malignant tumors and active osteitis which together comprised about half of the studied cases.

Lymphographic changes caused by lymph node metastases in carcinoma of the suprarenal glands.

In the literature reviewed, only two articles were found describing lymphographical changes caused by metastases of malignant adrenal tumours. A patient with anaplastic carcinoma of the suprarenal gland is presented here. In this patient, postoperative retroperitoneal lymphography with control films was of vital importance for the planning of post-operative treatment and follow-up.

Lymphatic dissemination of bone and soft tissue sarcomas: a lymphographic investigation.

The series consisted of 132 patients, 61 with primary bone sarcomas and 71 with primary soft tissue sarcomas. The patients were all evaluated by lymphography. The investigation included both patients who had not yet been treated and patients with suspected or confirmed metastases. All tumour diagnoses were confirmed microscopically. The findings as regards dissemination were based on clinical examinations, laboratory tests, roentgen examinations and lymphographies. In some cases, lymph node biopsies and surgical observations were also used. A total of 151 lymphographies were performed and 281 follow-up films taken. Preoperative lymphography was performed using the technique introduced by Kinmonth. For postoperative lymphography on the stumps of amputated extremities, two simple but useful methods were developed, which are presented here. Changes in the lymphographic appearance of lymph node metastases, the occurrence of new metastases, and the results of treatment were assessed by survey films and repeat lymphography. The generally accepted criteria for metastasis were used as a basis for the analysis of the lymphographic findings. The results may be summarized as follows: 1. Incidence of lymphatic dissemination. Different sarcomas varied greatly in their clinical course, including the frequency of dissemination. The lymphatic involvement in the metastatic cases was as follows: Bone sarcomas: 16 out of 28 (Table 10); of these, 13 were to regional lymph nodes, 8 to distant nodes and 5 to both (Table 14). Soft tissue sarcomas: 24 out of 40 (Table 11). All 24 had metastases in regional nodes, and 8 in distant nodes as well (Table 15). The highest frequencies of lymphatic spread in the different metastasized tumours were found to be: Bone sarcomas: reticulosarcoma 100%, Ewing's sarcoma 50%, osteosarcoma 47%. Soft tissue sarcomas: rhabdomyosarcoma 100%, synovial sarcoma 80%, neurogenic sarcoma 78%, leiomyosarcoma 67%. 2. Time-relation between lymphatic and haematogenic dissemination; The tendency to metastasize first via the lymphatics or via the blood vessels varied. Half of the cases of Ewing's sarcoma and reticulosarcoma had evidence of lymphatic spread before blood-borne metastases were detected. In the osteosarcoma cases, however, lymphatic dissemination was always preceded by haematogenic spread (Table 12). In synovial sarcoma, rhabdomyosarcoma and neurogenic sarcoma, the first dissemination was more frequently lymphatic than haematogenic (Table 13). 3. Possible existence of special lymphographic features of sarcoma metastases. Only reticulosarcoma displayed special characteristics. The lymph node metastases of reticulosarcoma of bone had lymphographic appearances similar to those found in reticulosarcoma of soft tissue or lymph node origin (Fig. 12). The lymph node metastases of other primary bone and soft tissue sarcomas had no specific lymphographic features and were indistinguishable from carcinomatous metastases (Figs 7, 9, 13, 15, 18, 19, 20, 22, 23). 4...

Myocardial imaging using selective intracoronary injection of Thallium-201.

After selective coronary arteriography 150 muCi of Thallium-201 was injected into each coronary artery. Scintigraphy of the myocardium was performed about half an hour after the injection. In a series of ten patients the myocardium was clearly visualized in the gamma images. No adverse effects were noted.

Collateral circulation before and after coronary artery reconstruction.

The changes in collateral circulation after coronary artery reconstruction were analyzed in 75 patients with 177 bypass grafts and 18 complementary gas endarterectomies. The quantity of collateral circulation was directly proportional to the degree of coronary obstruction. The changes in collateral circulation depended on the success of coronary surgery or on the progression of the disease in coronary vessels. So, when the grafts remained patent, the collaterals disappeared and when the grafts became occluded, the collateral circulation returned to the preoperative level. Progressive obstruction of the coronaries caused increased collateral circulation.

Radiographic changes of the revascularized femoral head.

Twenty-two necrotic femoral heads in young adults were radiologically followed-up after grafting with vascularized bone by comparing the preoperative and the postoperative state of the hip joint. Three parameters were observed and followed; the flattening of the femoral head; the degree of osteoarthrosis of the joint; and the degree of incorporation of the graft into the recipient bone. The results, expressed by index figures, showed that the femoral head flattened during the first two years postoperatively; that the maximal incorporation occurred during the same period of time; and that the appearance of postoperative osteoarthrosis was slow during the first year and increased subsequently. This numerical characterization of radiological findings allows systematic individual analysis after revascularization of the femoral head with bone grafts. It is also suited for comparisons between patients, between series of patients and of various treatment techniques. Furthermore, this quantification provides a numerical index that seems to correlate with the outcome of the treated hip joint.

Metrizamide myelography in patients with iodine allergy or previous adverse reactions to iodinated contrast media.

Twenty-seven metrizamide myelographies were performed in 26 patients who had a history of iodine allergy or adverse reactions to iodinated contrast media. Three of the patients had had adverse reactions from a previous myelography procedure. All patients received atropine, diazepam, and metoclopramide as premedication. In ten examinations corticosteroids were also given. No patient, during or after myelography, had any reaction that could be related to hypersensitivity to the contrast medium. The incidence of headache, the most frequent side effect, was almost the same in patients who had corticosteroids in their premedication (30%) as in patients without (35%). These observations indicate that metrizamide myelography may be performed despite previous adverse reactions to contrast media.

Sonographic measurement of vertebral dislocation in spondylolisthesis.

The vertebral dislocation in spondylolisthesis was measured by both sonography and roentgenography in 20 patients with spondylolysis and 6-28 mm of spondylolisthesis. The two methods were applied independently of each other. The difference between the sonographic and roentgenographic measure of vertebral dislocation was 0-3 mm (mean 1.3 mm). The accuracy of sonography is sufficient for clinical work. The advantage of sonography is that the radiation burden of patients with spondylolysis can be decreased by replacing roentgenographic follow-up with sonography.
