CTA improves, complicates management of PE
Researchers in Canada and the U.S. have found CT angiography to be as safe and accurate as ventilation/perfusion lung scans for ruling out pulmonary emboli. Results from what may be the first study of its kind suggest, however, that CTA could also spot many clinically irrelevant thrombi.
Researchers in Canada and the U.S. have found CT angiography to be as safe and accurate as ventilation/perfusion lung scans for ruling out pulmonary emboli. Results from what may be the first study of its kind suggest, however, that CTA could also spot many clinically irrelevant thrombi.
Dr. David R. Anderson and colleagues at one U.S. and four Canadian tertiary-care centers enrolled 1417 consecutive patients with suspected PE between May 2001 and April 2005. Patients were randomized to undergo either V/Q scanning (n = 716) or CTA (n = 701). Almost 20% of patients randomized to CTA were diagnosed with PE or deep vein thrombosis during the initial evaluation period, while 14.2% of patients in the V/Q scanning group had a similar diagnosis. Researchers cautioned that CTA could lead in many cases to unwarranted anticoagulant therapy. They published their findings in the Dec. 19 issue of the Journal of the American Medical Association.

April 24th 2024In a recent interview, Kenneth J. Pienta, M.D., discussed the impact of piflufolastat F18, current directions in research with other PSMA-targeted radiotracers and future possibilities for the role of PSMA PET in the imaging paradigm for prostate cancer.
Study Reveals Benefits of Photon-Counting CT for Assessing Acute Pulmonary Embolism
April 23rd 2024In comparison to energy-integrating detector CT for the workup of suspected acute pulmonary embolism, the use of photon-counting detector CT reduced radiation dosing by 48 percent, according to newly published research.
