Real-time ultrasonography as the primary imaging method in suspect renal pathology of adults.

In the material of 253 successive patients real-time ultrasound was used instead of urography as the primary imaging method of renal diseases. Ultrasound detected a tumour more reliably and more specifically than urography and detected hydronephrosis with sufficient reliability. In cases of pyelonephritis urography was more informative than ultrasound. In 'diffuse' parenchymal diseases both methods were quite unreliable.

Colonoscopic appearance of the remnant of the appendix after total inversion.

In a series of 395 total colonoscopies, an oblong smooth tumor was seen in the cecum of six patients corresponding to the remnant of the totally inverted appendix. All the patients had undergone a laparotomy during which the appendix was inverted. The histological examination demonstrated a uniform finding without any signs of polyp or malignancy. Our findings stress that the appendix fails to undergo necrosis after total inversion in some cases, in which the changes in the cecum can be readily identified by total colonoscopy.

Ultrasound and computed tomography of small asymptomatic haemangiomas of the liver.

Gray-scale ultrasound examinations were performed in 13 patients with 18 small asymptomatic haemangiomas of the liver and computed tomography in 10 of these patients. Different types of ultrasound images were found. One of them appeared as a well-demarcated area of increased echoes with an echo-free halo consisting of vessels, is probably characteristic for haemangioma. The other types of images are considered non-specific. The native CT scans demonstrated a well-demarcated spherical area with low attenuation in 8 cases and an area with attenuation similar to the liver in 4. After contrast medium injection, areas with lower attenuation were found in 7 cases, with irregular accumulation of contrast medium in the periphery in 4, and with distinct vessels in the periphery in one case, 2 haemangiomas had the same attenuation as the liver parenchyma.

Combined use of ultrasound and computed tomography in the evaluation of fetal intracranial abnormality.

Antenatal ultrasonic findings in two pregnancies with fetal intracranial abnormality were completed by taking a restricted number of computed tomography (CT) scans under ultrasonic control. General information achieved by CT was not greater compared with ultrasonography. CT demonstrated better than ultrasound the calcified areas in the intracranial teratoma of the fetus. In the case of fetal hydrocephaly the existence of a dilated, but otherwise intact cerebral ventricular system was established by CT after a somewhat controversial ultrasonic finding. CT can be used as a complementary examination when there are specific problems to be evaluated after antenatal ultrasonic scanning. CT should be used in these cases under ultrasonic control and the information of the both methods must be combined for the clinical decisions.

Abdominal ultrasonography and computed tomography in von Hippel-Lindau disease.

47 subjects belonging to four families with von Hippel-Lindau disease were examined using ultrasound and computed tomography. The subjects had no abdominal symptoms. At renal examinations carcinomas in two, haemangioma in one and cysts in eight persons were detected. Pancreatic cysts were found in four persons. Ultrasound and computed tomography examinations of the visceral organs are easy, non-invasive and safe for members of families with von Hippel-Lindau disease. An annual ultrasound visceral follow-up examination is advisable to detect manifestations of the disease as these become more common with age. It is especially important to detect and treat renal cell carcinomas as early as possible.

The sonographic images of hypernephromas.

The sonographic images of hypernephromas were examined in 46 histologically confirmed cases. The echogenicity of hypernephromas can be higher, equal or lower that of renal cortex. There is no significant correlation between echogenicity and macroscopic vascularity. The infiltration of a tumour cannot be estimated with certainty using sonography. Acoustic enhancement can also be seen behind hypernephromas.

Correlation of double-contrast radiography and endoscopy in reflux esophagitis.

Esophageal double-contrast radiography was performed on 19 patients with endoscopically verified reflux esophagitis and on 12 patients with endoscopically normal esophagus. Using the findings at endoscopy as a reference, double-contrast radiography showed four false-negatives and one false-positive finding, its overall accuracy being 84%. In both double-contrast radiography and endoscopy, hiatal incompetence correlated poorly with the presence of any esophagitis. It was concluded that double-contrast radiography is the radiological method of choice in suspected reflux esophagitis, and that screening of the lower esophagus should be included in examinations of the upper gastrointestinal tract.

Transmission media for ultrasonography.

Demonstration of organ structures by ultrasonography is sometimes limited due to the gaseous contents of the gastrointestinal tract. Fluids or semifluids which have a variable acoustic transmission may be used to allow passage of the ultrasound through the obstructing boundaries. These material should not have too low an attenuation relative to soft tissues because then the fixed swept gain curve will cause an effective amplication of the posterior echoes. The materials should also not be too attenuating, thus limiting patient penetration. Various liquid transmission media were tested in their ability to eliminate gas deposits in the gastrointestinal tract. Meat soup was found effective in the stomach and Metamucil was found effective in the colon.

Gray-scale ultrasonography and jaundice.

Forty-nine consecutive jaundiced patients were examined with ultrasonography as the initial imaging method. In 90% could surgical and medical jaundice be differentiated and in 51% the correct specific diagnosis reached.

The venous drainage of the femoral neck as a prognostic sign in Perthes' disease.

The correlation between delayed venous drainage from the femoral neck and "head at risk" factors were studied in 47 patients (50 hips) with Perthes' disease. A good correlation was found between markedly disturbed venous drainage and "head at risk" factors. Lateral subluxation of the femoral head and Gage's sign correlated best with pathological venography. Thus a severely disturbed venous return from a hip with Perthes' disease seems to be a poor prognostic sign.
