Making RVU-based productivity assessment work for you
Implementing a physician workload management system may take some fine-tuning, but it can help a practice address productivity issues and increase output in the long run, according to healthcare consultant Melissa Dill, who spoke at the recent Medical Group Management Association (MGMA) meeting in San Francisco.

CAD may unmask unsuspected cancers in diagnostic mammo
Radiologists from California studied whether computer-aided detection (CAD) could enhance diagnostic mammograms, potentially picking up secondary cancers. They found that CAD systems could help radiologists identify cancers and suspicious areas that were not a clinical concern initially.

Real-time CT teamed with tracer tracks CED treatment
SAN FRANCISCO - The latest oncologic technique for treating tumors involves convention-enhanced delivery (CED). But determining whether CED was successful requires the development of imaging tracers for real-time, in-vivo monitoring, according to a presenter Monday at the Congress of Neurological Surgeons (CNS).

Will Etheridge's breast cancer up screening in gay community?
Melissa Etheridge's publicist announced last week that the singer has been diagnosed with breast cancer. Will Etheridge's cancer scare spur the lesbian community, which has a history of underutilizing screening, to take more interest in their breast health? Health researchers who study the community offer their opinions.

MRI clicks with TMJ diagnosis and treatment
Considering the uncertainties about TMJ causes and treatment, it's clear that imaging can play an important role in its management. European researchers recently found that MRI may be clinically useful in studying the articular disk and the joint, while a group in Seattle used MRI to evaluate TMJ disk position in patients who had undergone bilateral sagittal split osteotomy. However, MRI's cost can be a disadvantage, according to researchers in Austria.

Ultrasound alters management of infants with genitourinary disorders
SAN FRANCISCO - Echogenicity is a better predictor of renal function than parenchymal thinning on postnatal ultrasound, according to a presenter at the American Academy of Pediatrics (AAP) meeting. This sonographic data can help clinicians prognosticate the outcome of further radiological testing, as well as counsel patients and their families.

MR more likely than mammo to expose multiple malignancies in dense breasts
MRI is considerably more sensitive than mammography for detecting multiple malignant foci in women with extremely dense breasts, according to a study in the American Journal of Roentgenology. However, the modality doesn’t quite hit the mark in women with fatty breasts.

LI-RADS ultrasound surveillance version 2024 improves HCC detection
By Amerigo Allegretto
The 2024 version of the LI-RADS Ultrasound Surveillance system improves detection of hepatocellular carcinoma (HCC) over earlier iterations.

(A,B) Images from an initial ultrasound examination showed no identifiable lesions and received a consensus ultrasound category of US-1. Nearly the entire liver is visualized, with minimal shadowing (“s”, A and B), and the examination received consensus result of VIS-A. The AFP level was 7.1 ng/mL on assessment six months before the ultrasound, 9.1 ng/mL on assessment three months before examination, and 14.2 ng/mL on assessment on exam day. The AFP result was thus assessed as positive based on a progressive increase on two consecutive tests. The atient was considered to have negative surveillance result according to LI-RADS Ultrasound Surveillance v2017, but positive surveillance result according to LI-RADS Ultrasound Surveillance v2024. (C-D) Axial arterial-phase (C) and portal-venous phase (D) T1-weighted images from subsequent gadoxetic acid-enhanced MRI show a 2-cm arterial-phase hyperenhancing observation (arrow, C) with portal-venous washout (arrow, D) in segment 7. This observation was classified on MRI as LR-5, thus meeting the present study’s reference standard for diagnosis of HCC. The mass is located in the periphery of the liver, an anatomic area where ultrasound visualization can be challenging due to shadowing.

Images in a 74-year-old male patient who presented at the hospital with acute symptoms of a right hemispheric ischemic stroke and a National Institutes of Health Stroke Scale (NIHSS) score of 24. (A) Nonenhanced CT image shows no signs of early infarction, whereas (B) CT perfusion image shows a large perfusion deficit in the territory of the middle cerebral artery and anterior cerebral artery caused by an extracranial occlusion in the right internal carotid artery. (C) Digital subtraction angiography shows the occlusion in the C1 segment. The extracranial occlusion was passed, reperfused, and subsequently stented (D, E). The final contrast injection did not reveal any intracranial occlusions within the territory of the internal carotid artery (F). At the 24-hour follow-up, there was no infarction on (G) the nonenhanced CT image, and the NIHSS score had decreased to 3 points. Image courtesy of RSNA.
CEUS resolves indeterminate CT, MRI liver observations
By Amerigo Allegretto
Contrast-enhanced ultrasound (CEUS) can resolve some high-risk indeterminate liver observations initially seen on CT or MRI.
January 21, 2025
Images depict a 49-year-old female participant with cryptogenic cirrhosis who presented with a 3.2-cm liver lesion. This biopsy-confirmed hepatocellular carcinoma (HCC) with an initial categorization of Liver Imaging Reporting and Data System (LI-RADS) category LR-4 (probably HCC) at CT was upgraded to LR-5 (definitely HCC) at contrast-enhanced ultrasound (CEUS). (A) Precontrast CT images in the liver show vague hypoattenuation in the medial left hepatic lobe (arrows). (B) Arterial phase images demonstrate no definite arterial phase hyperenhancement (arrows). (C) Washout and an enhancing capsule (arrows) on a late-phase image resulted in an LR-4 categorization. (D) B-mode ultrasound shows a round hypoechoic nodule (arrows). (E) An early-phase CEUS image shows clear arterial-phase hyperenhancement (arrows); (F) No washout at one minute (arrows), and (G) late, mild washout at four minutes (arrows) resulted in a CEUS LR-5 categorization.
