Dual-time-point FDG-PET improves pulmonary nodule assessment
By Jonathan S. Batchelor
LOS ANGELES - Researchers at the Society of Nuclear Medicine meeting outlined a protocol to improve the accuracy of pulmonary nodule FDG-PET imaging. The technique involves imaging patients at two time points versus traditional single-time-point PET.

CT, CAD techniques improve lung nodule detection
By Leslie Farnsworth
Two presentations at the 2001 RSNA meeting touted the benefits of multidetector-row CT for the detection of pulmonary nodules. A German group compared MDCT slice thickness to diagnostic accuracy, while researchers from New York City tested a computer-aided detection system for examining pulmonary abnormalities.

Whole-body CT preferred to chest x-ray, ultrasound in trauma patients
By Leslie Farnsworth
Standardized whole-body CT performed immediately after resuscitation in trauma patients provides better results than a targeted approach using CT, x-ray, or ultrasound, according to a study presented at the 2001 RSNA meeting.

Bigger not necessarily better for digital chest x-ray matrix
By Jonathan S. Batchelor
Although digital storage phosphor x-ray systems are capable of producing either 2K or 4K matrices for image acquisition, using the higher resolution may not provide a clinically relevant increase in image quality, according to radiologists from the University of Vienna in Austria.

Tips and techniques for decubitus and oblique chest x-rays
By Naveed Ahmad, MD
Lateral decubitus chest x-rays are helpful for determining effusions and pneumothorax. Oblique-view films may be requested for a clutch of reasons, such as determining the site of origin of an intrathoracic lesion. Dr. Naveed Ahmad concludes his series on chest x-ray techniques with step-by-step guidelines to positioning these views.
