To describe findings in, and the clinical course and outcome of, aortic dissection (dissecting aneurysm) caused by angiographic procedures. ⋯ Angiographers should be aware of this potentially serious complication. The extent and type of the aortic dissection can be determined with CT.

To determine the structures responsible for the left-sided indentation in right aortic arch (RAA) with aberrant left subclavian artery (ALSA). ⋯ The aortic diverticulum appears to be an important factor in the production of the left-sided esophageal defect in patients with RAA with ALSA.

One intact and one ruptured single-lumen implant were surgically placed in a rabbit. Magnetic resonance (MR) imaging was performed before and after surgical removal, and the ruptured implant was imaged after removal of the implant shell. Multiple curvilinear hypointense lines (linguine sign) were present in the MR images of the ruptured implant and of the implant shell alone immersed in saline solution but not in the image of the free silicone. The collapsed implant shell in a ruptured silicone implant does cause the linguine sign.

Dr Henry Garland: the man, the myth, the legend, and the legacy. Garland Lecture from the 1991 California Radiological Society meeting.
In a century of American radiology, a relatively small number of radiologists have emerged as unquestioned leaders of the specialty. One of those was L. ⋯ The Garland family has endowed an annual lecture at the meeting of the California Radiological Society. This essay is taken from the 1991 lecture, which was an assessment of Garland's significance.

Bedside chest radiography is one of the most frequently performed radiologic examinations, yet it is the examination with the most variation in image quality. The need to improve the quality of this examination has long been recognized, but it is a difficult problem to solve. Critically ill patients must undergo bedside chest radiography almost daily. ⋯ When grids are used, the image quality is improved; acceptance has been slow, however, because the grid is frequently misaligned. Storage phosphor imaging/computed radiography with grids is a technology improvement that almost completely solves this problem. Radiologists should be sure to optimize the current techniques, as well as provide prompt examination reporting.
