Abraham Kim[email protected]Advanced Visualization3D-printed breast biopsy device boosts accuracyResearchers from the Netherlands have developed a 3D-printed robot-guided device capable of facilitating MR-guided breast biopsy and improving the accuracy of breast cancer diagnosis. Biopsies can even be performed inside the MRI scanner.January 9, 2018CTDo more CT scans lead to more kidney surgeries?The higher the number of chest or abdominal CT exams in a hospital referral region, the greater the probability that patients will undergo a renal procedure, likely due to the incidental detection of renal masses, according to a study published online December 26 in JAMA Internal Medicine.January 8, 2018CTDoctors who order fewer CTPA scans detect more PETurns out that less really is more. Canadian researchers are reporting that doctors who order fewer CT pulmonary angiography (CTPA) scans for pulmonary embolism (PE) actually have a higher rate of successfully detecting the condition, according to a letter published online January 8 in JAMA Internal Medicine.January 8, 2018CTCT dose tracking highlights differences among kids in ERRadiation dose tracking software revealed that children who had CT scans in the emergency room (ER) of separate hospitals in Finland received considerably different radiation doses for head and cervical spine CT exams, according to a study published in Emergency Radiology.January 2, 2018CTRisk-based lung cancer screening tops USPSTF guidelinesUsing individual risk-based criteria to determine eligibility for CT lung cancer screening may avert more deaths from cancer than using current U.S. Preventive Services Task Force (USPSTF) guidelines, according to research published online January 1 in the Annals of Internal Medicine.January 1, 2018MRIGadolinium in fetuses almost entirely cleared via placentaOnly trace amounts of the gadolinium administered to pregnant monkeys cross the placenta and enter the fetuses, and most of this gadolinium quickly returns back to the mother's bloodstream for excretion, according to research published in the January issue of Radiology.January 1, 2018Advanced Visualization3D-printed model reproduces real prostate propertiesResearchers from Minnesota have used a 3D printer to generate patient-specific prostate models that offer the dimensions and physical properties of a real prostate while also mimicking its tactile sensation and pliability, according to an article published online December 6 in Advanced Materials Technologies.December 27, 2017Image-Guided Surgery3D printing aids simulation of CT- and MR-guided ablationWith the availability of a 3D printing material that's detectable on both CT and MRI, radiologists can simulate and practice complex image-guided cryoablation of head, neck, and spinal tumors using 3D-printed models, according to research presented at RSNA 2017.December 26, 2017CTHow often are lung nodules missed on CAC scoring scans?If an incidental lung nodule is present on a CT coronary artery calcium (CAC) scoring scan, how often is that nodule actually detected and worked up? Not as often as one might expect, according to researchers who analyzed the reasons why nodules might be missed in a presentation at RSNA 2017.December 20, 2017CTFFR-CT algorithm guides management of revascularizationA deep-learning algorithm that analyzes fractional flow reserve CT (FFR-CT) scans was able to determine almost as well as invasive FFR which patients suspected of having coronary artery disease should be referred for revascularization. The finding could lead to better, less-invasive care, according to a presentation at RSNA 2017.December 17, 2017Previous PagePage 53 of 63Next PageTop StoriesDigital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsLower limb amputation is an increasingly common major complication of advanced peripheral arterial disease and diabetes mellitus.MRI3D MRI technique helps plan treatment for pediatric heart conditionsWomens ImagingCould AI scoring help with managing DCIS?CTClinicians, beware: CT diagnostic accuracy varies by adnexal lesion typePractice ManagementRadiology coding update for 2026
