CT and 18F-FDG PET for noninvasive detection of splenic involvement in patients with malignant lymphoma.

Objective: The purpose of this study was to determine the sensitivity and specificity of (18)F-FDG PET, CT, and combined PET/CT in the detection of splenic involvement at initial staging of lymphoma.

Materials And Methods: A retrospective longitudinal analysis was performed on the records of 111 patients with proven lymphoma who had undergone PET and CT before and after treatment. CT scans were evaluated independently by two radiologists, and PET scans by two nuclear medicine physicians.

Mechanical thrombectomy for early treatment of massive pulmonary embolism.

We report our technique and results of percutaneous mechanical thrombectomy in a consecutive series of eight patients with massive PE. We also discuss the possible role of mechanical PE thrombectomy. Eight consecutive patients with acute massive PE, with or without hemodynamic impairment, were treated with mechanical thrombectomy.

Prospective study of color duplex ultrasonography compared with contrast venography in patients suspected of having deep venous thrombosis of the upper extremities.

Background: The optimal strategy for diagnosis of deep venous thrombosis (DVT) is less well established for the upper extremities than for the lower extremities. Duplex color ultrasonography can be difficult to perform in the upper extremities because of their anatomy, and contrast venography is often indicated. Moreover, limited data exist on the use of duplex color ultrasonography in this setting.
