Lightweight cassette for mobile-unit radiography.

The authors have developed a cassette system for mobile-unit radiography, using a soft-vinyl cassette in a Lucite housing faced with aluminum. This system performs as well as conventional radiographic cassettes and weighs approximately one-half to one-third as much.

Esophagitis caused by oral medication.

Three cases of esophagitis caused by oral medication are reported: 2 were the result of prolonged use of quinidine tablets (producing focal subacute inflammation mimicking carcinoma in one and stricture in the other) and one occurred soon after ingestion of liquid KCl. Previous reports have implicated KCl tablets ("slow KCl"), tetracycline and doxycycline capsules, and ferrous sulfate tablets. The factors predisposing to this uncommon complication of oral medication are discussed. In all reported cases caused by KCl tablets, left atrial enlargement was present as the result of mitral stenosis.

Urographic and angiographic changes in acute unilateral pyelonephritis.

The pyelographic and angiographic changes in acute unilateral bacterial pyelonephritis are illustrated in our series of 12 patients. The radiographic abnormalities were completely reversible within a few weeks after clinical recovery. Complications (abscess) occurred in only one patient. Unilateral renal enlargement, diffuse or focal, impaired or absent excretory function, and attenuated calyces were the predominant findings; non-obstructive pelvicalyceal and/or ureteral dilatation were infrequent. Angiographic studies (fivepatients), performed to rule out vascular occlusion, tumour or carbuncle, showed attenuated and somewhat stretched intrarenal vessels associated with the diffuse or focal cortical swelling. Occasionally, a characteristic striated nephrogram is seen.

Ghost infantile vertebrae and hemipelves within adult skeleton from thorotrast administration in childhood.

In 2 adults who had received thorotrast intravenously at ages 2 and 3 years, respectively, radiopaque outlines of their infantile vertebrae were seen in the adult vertebrae. Similar "ghosts" of the hemipelves were present in the pelvis of 1 patient. Autopsy findings and autoradiographs in 1 patient strongly suggest that persisting thorotrast deposits in the infantile vertebrae and pelvis have produced a chronic radiation osteitis and dense thickened bone trabeculae, which are more radiopaque than the surrounding adult bone.

Chondroblastoma of the calcaneus: radiographic features with emphasis on location.

Fourteen cases of chondroblastoma of the calcaneus have been examined and the radiographic features described. Thirteen occured in males. In all but one case the location was either at the talocalcaneal articulation or adjacent to the posterior calcaneal cortex. A sclerotic margin was present in all instances. Occasionally calcifications and septations were seen.

Equipment vibration and radiographic image resolution.

Accelerometer transducers were employed to detect linear vibratory motions in various radiographic equipment during film exposure. Vibratory displacements sufficient to degrade the image were found in several spot-film devices and Bucky drawers. Other potential sources of image degradation are discussed.

New technique for ultrasound imaging.

A new system of ultrasonic imaging has been developed which utilizes optical interferometry. This system has a broad frequency range, wide angular response, and good resolution. Operation of the system and the results of experimental imaging are described. Application of this technique to the evaluation of in vitro tissue specimens demonstrates its capability for characterization of ultrasonic tissue properties.

Calcified intraperitoneal metastases from ovarian carcinoma.

Three cases of calcified ovarian metastatic carcinoma are reported in order to illustrate their principal forms and distribution. These cases also demonstrate unusual features of serosal, colonic, and gastric invasion; ureteral obstruction by a calcified metastasis; and active uptake of technetium diphosphonate by the metastatic lesions. Plain films often simulate retained colonic barium.

Granular cell myoblastoma of the lung.

Three cases illustrate the principal clinical and roentgenographic varieties of granular cell myoblastoma (GCM) of the lung. The vast majority are small benign intrabronchial tumors without roentgenographic findings. These remain asymptomatic and are detected accidentally at autopsy, surgery, or bronchoscopy (Case III). Larger obstructing lesions (Case I) cause focal atelectasis or pneumonitis, leading to cough, expectoration, and hemoptysis. Hilar enlargement from reactive lymph node hyperplasia is common. Clinically and roentgenographically these are indistinguishable from bronchial adenomas. Least often the tumor extends entirely extrabronchially (Case II) presenting as a parahilar parenchymal asymptomatic nodule, simulating a granuloma, hamartoma, arteriovenous malformation or a neoplastic nodule.
