[Value of computed tomography for the assessment of lymph node metastases in ovarian cancer].

The value of CT for demonstrating iliac and retroperitoneal lymph nodes involved by ovarian carcinoma was examined following primary or secondary laparotomy in 62 patients. CT had an accuracy of 74%, sensitivity of 80%, a specificity of 67%; there were false negatives in 20% and false positives in 33%. Local tumours of grade I and II, with no evidence of retroperitoneal metastases and normal palpation, must have intra-operative lymph node biopsies in order to exclude micrometastases. Under these circumstances, pre-operative lymphography need not be carried out.

[CT and ERCP as a combination research method in pancreatic diseases].

The value of combined CT and ERCP for studying the pancreas has been assessed in a retrospective study. CT and ERCP used singly provided a correct diagnosis in 74 and 63% respectively; the combination of these methods increased diagnostic accuracy to 86%. ERCP is employed after CT and is indicated if the pancreas appears normal, if there is suspicion of chronic pancreatitis or neoplasia, for elucidating focal masses or if there is obstructive jaundice, without its cause being visible on CT.

[Computed tomography of chondrogenic tumors].

The computed tomography (CT) morphology of chondrogenic tumors and the utility of CT in their diagnostic work-up is presented on the basis of 19 cases. CT provided unique informations regarding definition of tumor extent and tumor relationship to adjacent structures particularly in the axial skeleton. CT has diminished the indications for angiography in chondrogenic tumors.

[Computer tomography of mycotic aortic aneurysm].

The CT findings in 2 patients with mycotic aortic aneurysms are presented. CT was helpful in establishing the diagnosis by detecting the presence of aneurysms surrounded by an abscess and reactive enlargement of the lymph nodes. CT should be the first investigation for patients with suspected aortic aneurysms and with fever of unknown origin.

Value of computed tomography and lymphography in staging carcinoma of the uterine cervix.

CT scanning was performed on 68 consecutive patients with newly diagnosed, untreated carcinoma of the uterine cervix (FIGO stage IB-IVA). Lymphography was performed in 61 cases. Surgical pathological correlation was obtained in 16 patients. CT and clinical stage accorded only in 68%, mainly because of CT errors in the determination of parametrial involvement. CT detected enlarged lymph nodes in 60.5%, compared to 39.5% of cases with lymphographically demonstrated nodal metastases; this discrepancy resulted mainly from the inability of CT to discriminate benign nodal changes. Our data suggest lymphography as radiological staging procedure in early stage (IB, IIA) carcinoma and the routine use of CT in advanced stage (IIB-IV) disease.

Lymphography and computed tomography in staging nonseminomatous testicular cancer: limited detection of early stage metastatic disease.

The efficacy of lymphography and computed tomography (CT) in staging nonseminomatous testicular cancer was analyzed in 41 patients. Retroperitoneal lymphadenectomy in 30 patients with early tumor stage revealed 56% sensitivity, 90% specificity, and 80% overall accuracy for lymphography; CT was less accurate (44% sensitivity, 81% specificity, 70% overall accuracy). The presence of advanced disease in 11 patients was depicted equally by lymphography and CT, but CT better demonstrated the anatomic extent of the metastases. CT is valuable for discriminating between advanced and early tumor stages; the similar inaccuracy of lymphography in early disease militates against its routine and complementary use; retroperitoneal lymphadenectomy then remains the only accurate staging modality.

[Computer tomography in cancer of the renal pelvis].

The value of computer tomography in the investigation of carcinomas of the renal pelvis was analysed in 22 patients. In 88% of cases it was possible to differentiate tumours confined to stages I and II from tumours in the advanced stages III and IV. Computer tomographic signs of stages III and IV were demonstration of infiltration into the surrounding tissues and into the renal parenchyma as well as the presence of regional lymph node metastases. Computer tomography should follow urography wherever there is a suspicion of a pelvic carcinoma in order to define the tumour more precisely.

[Computer tomography in acute pyelonephritis].

Computer tomography of the kidneys was performed on 30 patients with acute renal infections (acute suppurative pyelonephritis, acute renal abscess, infected cyst, pyelonephrosis, calculus perforation, retroperitoneal abscess). Computer tomography provided more accurate information concerning the extent of the renal and extra-renal inflammatory process than did the urogram or sonogram. This may significantly affect the choice of treatment, particularly concerning the use of drugs or of surgery. Angiography and retrograde pyelography may be used in selected cases, especially where there is a suspicion of acute bacterial nephritis, renal vein thrombosis or ureteric obstruction.

[Current value of sonography in pancreas diagnosis].

The topical value of sonography in pancreas diagnosis is examined and discussed in a retrospective study comprising 264 patients. In 80% of the cases sonography can supply clear results if conditions of examination are optimal. Sonography is of excellent value in examining the normal pancreas (88%) and in identifying a pancreatic pseudocyst (93%) and carcinoma of the pancreas (87%). The sonographically guided fine-needle puncture enables cytological verification in more than 60% of the cases of carcinoma of the pancreas by detecting the presence of malignant cells. Invasive investigation methods are used on-target. Thanks to its high power of resolution, computerized tomography is considered as the method of choice in the diagnosis of inflammatory diseases of the pancreas and in clarifying a sonographic finding which lacks clarity. Today the emphasis of ERCP is mainly on detecting ductal changes when suspecting chronic pancreatitis or carcinoma of the pancreas.

[Computer tomography-guided puncture of the retroperitoneal space].

A CT-guided fine-needle puncture was performed in 42 patients with renal or retroperitoneal space-occupying growths identified by means of computed tomography. In 18 out of 24 patients (75%), CT-guided fine-needle puncture enabled verification of malignant neoplasias, relapses and metastases by means of identification of malignant cells. In 9 out of 13 patients suspected of retroperitoneal abscess, fine-needle puncture helped to establish the diagnosis by a positive bacteriological finding. In 5 cases, CT-guided anterograde pyelography and percutaneous nephrostomy were effected after puncture of the renal pelvis by means of sonography had failed. CT-guided puncture should be used as an additional or complementary examination over and above computed tomography alone whenever a space-occupying growth is present the aetiology of which remains unclear. CT-guided puncture is indicated on principle in retroperitoneal space-occupying growths which cannot be properly defined by sonography.

[Computer tomographic densitometry of the normal vertebral body spongiosa].

The absorption values of cancellous bone of the third lumbar vertebral body were measured in 80 patients by CT. It was possible to demonstrate a statistically significant linear correlation between absorption values and patient age. The older the patient, the lower the average absorption values of cancellous bone. The average absorption values in patients between 20 and 30 Jrs. were found to be about 200 HU, between 30 and 50 Jrs. 180, between 60 and 70 Jrs. 120 and between 70 and 80 Jrs. 100 HU. Although correlation between calcium salt content and absorption of bone under CT are well known, there are other factors (mainly fatty involution of bone marrow) who influences the absorption behaviour of cancellous bone.

[Computer tomographic-directed fine needle aspiration biopsy of pelvic masses].

CT-aided fine needle biopsy was performed in 48 patients with pelvic space-occupying lesions demonstrated by computer tomography. Amongst 36 patients with malignant neoplasms, recurrences or metastases, malignant cells were found in 26 (72%). In six out of twelve patients suspected of having a pelvic abscess, fine needle puncture confirmed the diagnosis by providing positive bacteriological results. CT-aided puncture should be used in conjunction with computer tomography in order to clarify the aetiology of space-occupying lesions. The indication for CT-aided puncture is the presence of a pelvic space-occupying lesions which cannot be demarcated by sonography.

[Computed tomographic staging of prostatic cancer].

77 patients with carcinoma of the prostate (stage T1 = 4, stage T2 = 17, stage T3 = 28, stage T4 = 28) were investigated by computerized tomography for staging. Intracapsular stage T1 tumors could not be identified as such. About 50% of clinical stage T2 tumors were shown to be of stage T3 by CT, whereas one fifth of the clinical stage T3 tumors were overestimated as demonstrated by CT. The extension of stage T4 tumors was more accurately depicted by CT then by clinical investigation. Inspite of the high diagnostic accuracy of CT for detecting regional lymph node metastases diagnostic lymphadenectomy is necessary prior to any major surgical intervention.

[Computer tomographic guided fine needle puncture of abdominal masses].

CT-guided fine-needle aspiration biopsy was carried out in 177 patients with proven intra-, retro- or extraperitoneal lesions. This method verified the diagnosis in 89/132 cases (66%) with malignant neoplasia, metastases and recurrent malignant tumors. In 45 patients with benign or inflammatory lesions of the intra- and retroperitoneal space, fine-needle puncture showed a purulent liquid, inflammatory altered cell elements or a positive bacteriological result. The success of CT fine-needle puncture depends mainly on the examiner's experience, the exact localization of the needle, and careful handling of the cytological material. Fine-needle puncture should be applied simultaneously with CT when an undefined space-occupying lesion is present. Unsuccessful sonography is an indication for CT-guided fine-needle puncture.
