Dearbhla O'Dwyer and Dr. Stefano CiattiUltrasoundCase study: Complete rectus femoris tear in an adolescent soccer playerA valuable tool in evaluating rectus femoris tears, ultrasound can be used to assess the size of the rupture, rule out other conditions, allow longitudinal assessment, and eventually guide the evacuation of the hematoma. Sonographer Dearbhla O'Dwyer and Dr. Stefano Ciatti discuss one case of a complete rectus femoris tear in an adolescent soccer player.June 15, 2008UltrasoundPictorial essay: 3D ultrasound reveals shoulder pathologyThe correct diagnosis of shoulder pathology is important but can be challenging. In a pictorial essay, sonographer Dearbhla O'Dwyer and Dr. Stefano Ciatti explain why ultrasound is up to that challenge. In particular, they discuss the value of 3D sonography for the presentation of soft-tissue structures and the overall visualization of shoulder disorders.March 20, 2008Page 1 of 1Top StoriesMolecular ImagingWhole-body PET shows how naloxone blocks opioidsPET imaging has shown for the first time how the opioid overdose treatment naloxone blocks neuroreceptors throughout the body.Womens ImagingKomen rails against proposed federal cuts to women's health programCTCT muscle metrics could help screen for sarcopeniaWomens ImagingCancer incidence on rise in younger people, womenAssociationsFinancial shock waves strike close to radiology researchers
![Images depict axial MRI scans in a 50-year-old premenopausal female patient with biopsy-proven 12-mm invasive lobular cancer in the lower outer quadrant of the left breast. Upper images are subtracted dynamic contrast-enhanced (DCE) MRI scans from the first and second postcontrast acquisitions. Lower images are ultrafast MRI scans obtained within 24 hours after the DCE study (four consecutive subtracted dynamic frames from time points [T] 6–9). There is marked background parenchymal enhancement (BPE) on the DCE MRI scans. Thus, the known cancer (arrow) is barely visible; it exhibits only slightly stronger enhancement than the normal fibroglandular tissue, which results in low conspicuity. At ultrafast MRI there is less BPE, and still the cancer is barely visible because it starts to enhance simultaneously with the BPE. The conspicuity of the cancer is even reduced compared with the DCE series. Both of the readers missed this cancer on both the DCE and ultrafast MRI scans.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2025/05/2025-05-06-rsna-ultrafast-dce-mri-breast.Gzvq76udFr.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
