Jacqueline Hewett[email protected]Radiation Oncology/TherapyQA records shed light on radiotherapy patient errorsThe computerization of radiation therapy planning and treatment can be a double-edged sword, both reducing and increasing the risk of errors. But computerization does make treatment safer, according to a 10-year analysis of errors at Memorial Sloan-Kettering Cancer Center in New York City.May 16, 2012Radiation Oncology/TherapyTiny oxygen generator boosts radiotherapyA tiny oxygen generator that can be implanted directly into the hypoxic center of tumors using a biopsy needle has been unveiled by researchers in the U.S. The micro-oxygen generator could potentially improve the efficacy of radiotherapy.November 1, 2011Radiation Oncology/TherapySoftware estimates motion effects for proton dose planningTumor motion due to respiration is a serious problem when it comes to ensuring that a scanned proton beam delivers the planned dose to a given target volume. Now, software simulating the delivery of a scanning proton beam to a moving lung tumor is resolving this problem.October 31, 2011Radiation Oncology/TherapyGold nanoparticles boost radiotherapy efficacyBy using gold nanoparticles with conventional megavoltage x-rays, researchers are predicting that tumor vasculature will receive a significant enhancement in local dose. Not only could this dose boost promote vascular shutdown in tumors, the hope is that it will suppress metastases and improve patient outcomes.February 16, 2011Page 1 of 1Top StoriesMRICNN techniques outperform conventional DL for Alzheimer's diagnosisConvolutional neural network (CNN) techniques outperform conventional deep learning (DL) methods in diagnosing Alzheimer's.Womens ImagingAbout half of women undecided on AI's use in breast imagingISMRMISMRM president outlines key highlights of the upcoming annual meeting in HonoluluMolecular ImagingSPECT/CT MPI may guide medical therapy in CAD patientsMRIAI model uses MRI data to predict brain cancer patient survival
![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)
