Thrombus resolution and hemodynamic recovery using ultrasound-accelerated thrombolysis in acute pulmonary embolism.

Purpose: To evaluate retrospectively the safety profile and clinical success of ultrasound-accelerated thrombolysis for acute pulmonary embolism (PE) with a standard lytic infusion protocol.

Materials And Methods: A retrospective study was performed at a single center treating patients with acute PE between October 2009 and April 2012. On diagnosis of submassive or massive PE by pulmonary computed tomography angiography or ventilation/perfusion scan, all patients received anticoagulation and treatment using the EkoSonic endovascular system (EKOS Corporation, Bothell, Washington).

Yttrium-90 radioembolization for liver malignancies: prognostic factors associated with survival.

Purpose: To identify key prognostic clinical and imaging variables in patients undergoing yttrium-90 radioembolization ((90)Y) for liver malignancies.

Materials And Methods: Patients with liver malignancies that progressed despite standard-of-care therapy were treated with (90)Y from 2002 to 2006. Baseline functional status, laboratory values, and diagnostic imaging were assessed before therapy.

Development of renal scars on CT after abdominal trauma: does grade of injury matter?

Objective: The objective of our study was to determine whether there is an association between the grade of a traumatic renal injury and the subsequent development of renal parenchymal scars on CT.

Materials And Methods: We performed a retrospective study encompassing all acute trauma patients admitted to our institution over a 42-month period found to have renal parenchyma injuries on initial MDCT and also to have undergone a follow-up CT performed at least 1 month after trauma. We identified 54 patients who sustained blunt (n = 44) or penetrating (n = 10) abdominal trauma.

Radiologic and pathologic characteristics of benign and malignant lesions of the mandible.

Mandibular lesions develop from both odontogenic and nonodontogenic origins and have varying degrees of destructive potential. Common benign cystic lesions include periapical (radicular) cysts, follicular (dentigerous) cysts, and odontogenic keratocysts. Benign solid tumors represent a broad spectrum of lesions such as ameloblastomas, odontomas, ossifying fibromas, and periapical cemental dysplasia.

Solitary fibrous tumor of the buccal space.

Solitary fibrous tumors are submesothelial mesenchymal fibroblastic tumors that typically occur in relation to parietal or visceral pleura. However, the tumor also occurs in extrapleural sites, including the peritoneum, mediastinum, orbit, and oral cavity. With the advent of immunohistochemical testing, certain tumors may be more readily identifiable; however, the diagnosis often must be reached by histomorphology and imaging studies alone.
