Randomized Controlled Trial Clinical Trial
Endovascular gamma irradiation of femoropopliteal de novo stenoses immediately after PTA: interim results of prospective randomized controlled trial.
To report an interim analysis of whether centered endovascular irradiation with the iridium 192 ((192)Ir) source immediately after percutaneous transluminal angioplasty (PTA) of de novo femoropopliteal stenoses lowers the restenosis rate. ⋯ Endovascular irradiation with a centered (192)Ir source immediately after PTA of de novo femoropopliteal stenoses reduces the restenosis rate.

Comparative Study
CT and conventional and diffusion-weighted MR imaging in acute stroke: study in 691 patients at presentation to the emergency department.
To compare the diagnostic accuracy of computed tomography (CT) and magnetic resonance (MR) imaging in a consecutive series of patients at presentation to the emergency department with symptoms of acute stroke. ⋯ In the diagnosis of stroke in the early period (<12 hours after presentation), DW MR imaging is superior to conventional MR imaging and CT.

Comparative Study
Bone marrow abnormalities of foot and ankle: STIR versus T1-weighted contrast-enhanced fat-suppressed spin-echo MR imaging.
To compare short inversion time inversion-recovery (STIR) and T1-weighted contrast material-enhanced fat-suppressed spin-echo magnetic resonance (MR) sequences for depiction of bone marrow abnormalities of the foot and ankle. ⋯ STIR images and T1-weighted contrast-enhanced fat-suppressed MR images demonstrate almost identical imaging patterns, and diagnoses determined with these findings show little difference.

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 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.
