Eric Barnes[email protected]CTVC CAD application does well alone and as reader aidA new investigational computer-aided detection (CAD) application significantly improves the accuracy of virtual colonoscopy interpretation, both as standalone software without a radiologist and in a real-world, multireader environment.February 14, 2010Nuclear MedicineStudy to compare 320-row CT perfusion against SPECTFollowing up on the CORE 64 study that tested the value of coronary CT angiography vis-à-vis angiography, researchers have launched a new international trial to compare 320-detector-row CT perfusion to SPECT myocardial perfusion imaging for detecting early coronary artery disease.February 9, 2010Nuclear MedicineZero calcium score enough to send chest pain patients homePatients presenting to the emergency room with chest pain who have zero calcium scores on cardiac CT probably can be discharged with a low likelihood of adverse events on follow-up, according to a study published online February 8 in the Annals of Emergency Medicine.February 9, 2010CTOne-stop cardiac assessment evolves with dual-source CTU.S. researchers have used dual-source CT to pull off what only recently would have been impossible: dynamic evaluation of the time-resolved passage of contrast through the myocardium, according to a study published this week in the Journal of Cardiovascular Computed Tomography.February 9, 2010CTCATCH rules accurately predict which kids need head CTCanadian researchers have issued a new set of clinical rules for determining which injured children need head CT. They hope the new guidelines could help prevent unnecessary radiation exposure and costs associated with CT overuse, researchers said.February 8, 2010CTBJR: Prospective coronary CTA cuts cancer riskThe use of prospective gating in CT angiography (CTA) scans can dramatically reduce theoretical cancer risks associated with the heart exams -- by as much as 87% over retrospective gating -- according to a new study published online in the British Journal of Radiology.February 8, 2010CTSoftware enables ultralow-dose CCTA in arrhythmia patientsA new algorithm enables patients with arrhythmias to undergo the kind of ultralow-dose coronary CT angiography (CCTA) imaging once reserved for those with regular heartbeats. The technique paves the way for low-dose scanning in a new population of patients with suspected coronary artery disease.February 8, 2010Nuclear MedicineStress perfusion CT adds value to coronary CT angiographyCombined stress perfusion CT imaging not only is feasible, it's potentially valuable for assessing some patients at risk of coronary artery disease in a one-modality imaging procedure, according to a study appearing this month in Radiology.February 8, 2010CTEditorial: CMS unfairly held VC to higher standardWhen the U.S. Centers for Medicare and Medicaid Services (CMS) rejected reimbursement for screening virtual colonoscopy last May, it appeared to hold VC to a higher standard than other screening tests that are already approved, according to an editorial in the Annals of Internal Medicine.February 4, 2010CT320-row perfusion CT shows promise for pancreatic tumorsPerfusion CT with a 320-detector-row scanner offers improved resolution of pancreatic tumors due to its ability to image the entire organ without slice overlap, according to researchers from Berlin and Toronto.February 4, 2010Previous PagePage 131 of 258Next PageTop StoriesNuclear MedicineLLMs rapidly evolving in nuclear medicineLarge language models (LLMs) are widely used to handle the large volume of text data generated in nuclear medicine.MRIDWI with fat correction identifies liver scarring in MASLD patientsUltrasoundGhost scans problematic in POCUS trauma examsMolecular ImagingPSMA-PET may require selective use to be cost-effectiveSponsor ContentJoin Us!
