To investigate the natural history and predictors of progression of a newly developed ulcerlike projection in patients with an aortic intramural hematoma. ⋯ The location of ulcerlike projections is the principal predictor of progression, and careful follow-up study is needed for patients with an ulcerlike projection located from the ascending aorta to the aortic arch.
-
To retrospectively review time-resolved two-dimensional projection magnetic resonance (MR) angiographic data to characterize the passage of gadolinium-based contrast material down the leg arteries in patients undergoing peripheral MR angiography. ⋯ Contrast material injected intravenously traveled rapidly down the peripheral arteries at approximately 6 seconds per station, but a long arterial phase time window allowed bolus-chase peripheral MR angiography to function with slower table stepping. Patient-to-patient variations in contrast material kinetics may be anticipated on the basis of age, sex, and clinical parameters.
-
To determine the safety and efficacy of radio-frequency (RF) ablation for pain reduction, quality of life improvement, and analgesics use reduction in patients with skeletal metastases. ⋯ RF ablation of painful osteolytic metastases is safe, and the relief of pain is substantial.
-
To evaluate the ultrasonographic (US) findings in patients with a referring diagnosis of tennis leg and to explore the relative importance of the plantaris tendon and gastrocnemius muscle in the pathogenesis of this condition. ⋯ In patients with clinical findings of tennis leg who undergo US, abnormalities of the medial gastrocnemius muscle appear to be more common than those of the plantaris tendon.

To determine whether data from a professional society placement service--the Professional Bureau of the American College of Radiology--are a valid measure of the employment market. ⋯ The statistical significance levels of the correlations and the pattern of findings--namely, stronger correlations among measures of the same aspect of the employment market--indicate that these placement service data are valid and reasonably accurate measures of the employment market.
