Technical adequacy of fluoroscopic spot films of the gastrointestinal tract: comparison of residents and technologists.
OBJECTIVE: We compared images obtained during gastrointestinal fluoroscopy by specially trained and experienced technologists with those obtained by radiology residents to determine if the quality of images was similar between the two groups. MATERIALS AND METHODS: Three senior radiologists examined the fluoroscopic spot films of 80 patients who were divided evenly into four groups: barium enemas performed by technologists, barium enemas performed by residents, gastrointestinal series performed by technologists, and gastrointestinal series performed by residents. The senior radiologists graded adequacy of visualization of the esophagus, stomach, duodenum, and all parts of the colon. A grade of 1 was given for poor films, 2 for adequate films, and 3 for good films. They did not know who performed each study. RESULTS: For barium enemas, the residents' mean score was slightly higher than that of the technologists (13.5 compared with 12.9). For gastrointestinal series, residents' mean score was again slightly higher (20.5 compared with 19.7). In neither case did the difference reach statistical significance. CONCLUSION: Fluoroscopic films obtained by residents and by specially trained and experienced technologists for barium enemas or gastrointestinal series were statistically indistinguishable.
Disclosure of imaging findings to patients directly by radiologists: survey of patients' preferences.
OBJECTIVE: The purpose of this study was to determine if patients prefer to have radiologists tell them imaging findings immediately after the examination or if they prefer to hear the results later from their referring physician. SUBJECTS AND METHODS: A simple questionnaire was devised and distributed to 261 consecutive patients in the radiology department of a large university hospital. During a 10-day period, patients seen in several departmental sections (gastrointestinal, genitourinary, CT, sonography, mammography, chest, musculoskeletal) completed the questionnaire. Patients were asked if they wanted the radiologist to tell them if the results were normal; if the results were abnormal; if they would prefer to hear the results from their family doctor, internist, or other primary care provider; and if they felt entitled to an explanation of their test results. Results were tabulated and expressed as percentages. RESULTS: Analysis of the 261 questionnaires disclosed that 92% of patients wanted the radiologist to tell them if the results are normal. An additional 7% answered "Yes, but only if I ask." If the results are abnormal (cancer, for example), 87% wanted the radiologist to tell them. An additional 7% answered "Yes, but only if I ask." CONCLUSION: Our results show that most patients prefer to hear the results of imaging examinations from the radiologist at the time of the procedure rather than to hear them later from the referring physician, regardless of the findings.

Rectal diverticulosis: a case report and review of the literature.
The occurrence of rectal diverticulosis is rare. We report the incidental finding of a large rectal diverticulum in a patient receiving an air-contrast barium enema. The presence of uncomplicated rectal diverticulosis is probably of little clinical significance. However, there can be associated complications such as inflammation and perforation, and potential confusion with rectal carcinoma.
Radiological evaluation of prosthetic fit in below-the-knee amputees.
Fourteen artificial limbs in eight adult patients with below the knee amputations were evaluated for prosthetic fit by several radiological parameters. The best objective means of evaluation of prosthetic adequacy is piston action.
Left ventricular aneurysm in short axis: a comparison of magnetic resonance, ultrasound and thallium-201 SPECT images.
Short axis magnetic resonance images of a left ventricular aneurysm were compared to similar views obtained by echocardiography and by thallium-201 single photon emission computed tomography. Images of the dyskinetic left ventricular apex and the contractile left ventricular base were analyzed and compared. Unlike the previously reported orthogonal plane magnetic resonance images, short axis imaging provided representative and quantitative information in views comparable to those obtained by standard noninvasive imaging techniques. These data indicate that short axis magnetic resonance imaging is capable of identifying and sizing the aneurysmal and the residual segments of the left ventricle. The findings may be of prognostic value in patients with left ventricular aneurysm.
