Liposuction fat-fillant implant for breast augmentation and reconstruction.

The perfect breast implant fillant material would have higher viscosity than water and would be autologous and harmless. We describe the confinement of liposuction fat in implants using the Lipovacutainer during a routine liposuction procedure. This collected fat is prepared inside the Lipovacutainer and is reinjected through a Lipomedia filling cannula into a leaf valve implant as the fillant in place of saline.

CT of pseudohydronephrosis: hydroureter in a weight lifter.

A case of bilateral pseudohydronephrosis and hydroureter produced by markedly hypertrophied psoas muscles in a weight lifter is presented. Plain film and CT findings of the case are discussed together with the topographic anatomical explanation of the radiologic findings.

Computed tomography for the evaluation of knife impalement injuries: case report.

A patient with a stab wound to the back with suspected major vascular injury was evaluated by computed tomography instead of arteriography. The computed tomographic (CT) scan demonstrated no injury to the aorta, inferior vena cava, or esophagus, which were adjacent to the blade, and excluded a hematoma. The information from the CT scan made possible a less extensive surgical procedure than might have otherwise been necessary.

Paranasal sinuses: low-dose CT.

While computed tomography (CT) has become an important imaging modality in the evaluation of the paranasal sinuses, the radiation dose remains higher than is necessary. With use of a head phantom and constant kilovolt peak setting, axial and coronal CT scans of the paranasal sinuses were obtained at each of six successively lower milliampere second settings than are commonly used in clinical practice. Although noise, as measured by the standard deviation of the CT numbers, did increase, images were of diagnostic quality even when dose levels were reduced by a factor of 28.
