Endobronchial ultrasonography (US) with 4.5-F small-caliber US probes, combined with bronchoalveolar lavage technique, was evaluated in autopsied lungs and 22 patients with various pulmonary interstitial or alveolar diseases. Several different echoic patterns were found that may reflect changes due to pathologic alteration of lung parenchyma. This technique may have potential for evaluation and diagnosis of peripheral lung diseases.

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 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 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 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.
