Dr. Shamim MalikMRICase study: Baker's cystIn a Baker's cyst, fluid accumulates around the knee with the gastrocnemio-semimembranosus bursa, resulting in a herniation from the posterior aspect of the knee, through the gap between the medial head of the gastrocnemius and semimembranosus tendon. Dr. Shamim Malik of Kenya discusses a case of Baker's cyst, as well as the role of imaging in making the differential diagnosis.October 17, 2007CTCase study: Ovarian dermoid cystAt the Crater X-Ray Clinic in Nakuru, Kenya, Dr. Shamim Malik's patient population is a rural one, consisting mostly of manual laborers and subsistence farmers. A contrast-enhanced pelvic CT scan runs about $90 (6,000 Kenya shillings). In this report, Malik shares the results of a CT exam on a patient who presented with pelvic pain.June 20, 2007Page 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)
