Eric Barnes[email protected]CTPerfusion CT predicts, measures, thrombolysis benefit after acute strokeAs CT and MRI vie for supremacy in stroke assessment, perfusion CT (PCT) is earning points for its ability to clearly delineate both infarct and penumbra. Radiologists who perform the functional CT test are gaining confidence in their methods -- and are using them increasingly to predict which patients are likely to benefit from thrombolytic therapy.December 23, 2003CTResults suggest important new cancer staging role for virtual colonoscopyBeyond screening for colorectal cancer and polyps, virtual colonoscopy could someday play a leading role in cancer staging. A new study from Italy suggests that, for at least the second time this fall, virtual colonoscopy has outperformed its conventional counterpart -- this time in patients with known or suspected colorectal carcinomas.December 18, 2003CTAuntMinnie.com Virtual Colonoscopy Radiology InsiderVirtual colonoscopy got its first 15 minutes of fame on the first of December, when Navy radiologist Dr. Perry Pickhardt announced the results of his group's groundbreaking multicenter trial at the 2003 RSNA meeting. AuntMinnie members had gotten the news six weeks earlier.December 14, 2003CTVirtual colonoscopy accuracy suffers when radiologists work too fastThere is much talk, and some evidence, that innovations such as CAD and primary 3-D reading will soon smooth out the rugged learning curve for virtual colonoscopy providers. But no matter what legions of computer programmers might come up with, at the end of the day it’s still radiologists who are responsible for the data -- and a new study suggests that experience and confidence can work against them.December 11, 2003CTResearchers determine optimal MDCT protocols for liver imagingCHICAGO - Multislice CT comes with far too many exposure choices, so it’s always good news when researchers take the time to determine the optimal settings in some anatomic region or other. In this case it’s isotropic liver imaging, offered up by Dr. Min Ju Kim and colleagues from the Sungkyunkwan University School of Medicine in Seoul, Korea.December 3, 2003CTVC finds all masses after conventional colonoscopy fails in its missionCHICAGO - Virtual colonoscopy had a high predictive value for the presence of colorectal masses after failed colonoscopy, according to researchers from the Beth Israel Medical Center in Boston. There were too many false-positive findings among the larger polyps, but VC still succeeded in detecting the most important lesions.December 2, 2003Clinical NewsRFA shows high success rate in lung tumor ablationCHICAGO - Radiofrequency ablation isn’t just for livers anymore. The percutaneous technique is proving to be a viable option for zapping lung cancer, according to the results of a prospective multicenter trial led by Dr. Riccardo Lencioni from the University of Pisa in Italy, and joined by centers in Australia, the U.S., the U.K., and Austria.December 1, 2003CTInternational committee of CT users and vendors settles on mass as the standard measurement of coronary calciumCHICAGO - The Agatston score has officially been replaced by calcium mass for coronary artery calcium assessment. It has, at least, in the eyes of an international consortium of radiologists, physicists, and vendors that has labored for four years to settle on a new standard designed to work as well for electron-beam CT (EBCT) scanners as it does for multidetector-row CT (MDCT) machines.December 1, 2003CTKarachi connection: CT best for busting heroin smugglersCHICAGO - These days the long arm of the law is reaching deep into suspected drug-smuggling operations in Pakistan -- in some cases right into the bellies of suspected drug traffickers. In cases referred by customs officials, radiologists in the port city of Karachi are now using abdominal ultrasound, x-ray and CT to thwart so-called "body packers" who swallow capsules of heroin before attempting to leave the country.November 30, 2003CTThinner collimation improves polyp detection -- sometimesThe jury has not yet rendered a verdict on the value of thin-section CT slices in colorectal polyp detection, but the lengthy trial is at least moving forward. Among the questions presented in cross-examination: Does tighter longitudinal resolution really improve the ability to find lesions in virtual colonoscopy? And if so, are the additional findings the ones that radiologists really need to see?November 25, 2003Previous PagePage 225 of 258Next PageTop StoriesPractice ManagementTurnover increasing among radiology practicesExcessive workload, being a female, and working in nonacademic practices are tied to higher turnover among imaging practices.CTFibrosis pattern on CT predicts CPFE progression rate, but not survivalUltrasoundCould less ultrasound lead to less thyroid cancer overdiagnosis?Nuclear MedicineGenetic mutations linked to poor outcomes in Pluvicto patientsSponsor ContentHow Agentic AI Is Transforming Radiology Ops
