Comparative StudyAcute pulmonary embolism: value of transthoracic and transesophageal echocardiography in comparison with helical CT.
The goal of this study was to prospectively compare the accuracy of transthoracic and transesophageal B-mode and Doppler echocardiography with helical CT for detecting acute pulmonary embolism. ⋯ In comparison with helical CT, transthoracic and transesophageal echocardiography had limited accuracy for detecting pulmonary embolism.

False aneurysm of the pulmonary artery induced by a Swan-Ganz catheter: clinical presentation and radiologic management.
This study evaluates retrospectively the clinical presentation, radiographic findings, and angiographic management of false aneurysm of the pulmonary artery resulting from Swan-Ganz catheter placement. ⋯ Even when the chest radiograph appears unremarkable, patients clinically suspected of developing a false aneurysm of the pulmonary artery after Swan-Ganz catheter placement require enhanced CT or pulmonary angiography to establish the diagnosis. False aneurysms of the pulmonary artery can be treated at the time of pulmonary angiography by steel-coil embolization.

The purpose of this study was to assess the additional yield of a repeat skeletal survey in identifying and dating skeletal injury for cases in which child abuse was strongly suspected. ⋯ When child abuse is strongly suspected on the basis of the findings on the initial skeletal survey, other imaging studies, history, or physical examination, a follow-up skeletal survey is recommended to provide a through and accurate assessment of osseous injuries.

The purpose of this study was to evaluate thin-section helical CT for the frequency of visualization of the peripancreatic veins, the venous anatomy at the head of the pancreas, and variations of the venous anatomy. ⋯ Thin-section helical CT scans provide good visualization of the peripancreatic veins.
