Prostate imagers await 3T endorectal coils

March 06, 2005

Under the best of circumstances, 3T imaging of the prostate with a body coil can approximate the level of detail and sensitivity available at 1.5T with an endorectal coil. Researchers hope that with a 3T-oriented endorectal coil they will finally be able to take advantage of 3T's higher resolution in a challenging portion of the anatomy.

Report from RSNA: CTA nails down role of gold standard for pulmonary embolism

December 16, 2004

Whether it scans in four slices or 16, CT is the method of choice for detecting pulmonary emboli, researchers said at the RSNA meeting. Even four-slice technology boasts a negative predictive value greater than 99%, better than ventilation/perfusion (V/Q) studies or conventional pulmonary angiography.
