Normal glandular prostate tissue on MRI gives no signal reduction on the ADC map and no increase in signal intensity on the high b-value images (PI-RADS 1). (nature.com)
MR FDG is the Ki multiplied by the blood glucose value, whereas DV reflects the free 18 F FDG available prior to the beginning of phosphorylation of FDG, which is an estimate for the vascularity and interstitial fluid components of the tissue being evaluated. (siemens-healthineers.com)
The right lung base lesion (2.06 cm in longest diameter) is of similar size to the mediastinal metastases (2.36 cm longest diameter) but with significantly lower SUV max and MR FDG and slightly higher DV, which suggests an inflammatory lesion with a lower level of glucose utilization and slightly higher vascularity and interstitial fluid related to inflammation-related tissue fluid retention.

Therefore, MRI has become increasingly available for men with elevated prostate-specific antigen levels to detect prostate cancer based on the Prostate Imaging and Reporting and Data System (PI-RADS). (pfmjournal.org)

MRF is, thereby, expected to be much more accurate and reproducible than traditional MRI and should improve multi-center studies and significantly reduce reader bias when diagnostic imaging is performed. (springer.com)

Process of making the patient-specific sectioning-mold from the MRI imaging: (a) prostate MRI images, (b) segmentation, (c) patient-specific prostate model, and (d) 3D-printed mold with knife slots for 6mm sectioning. (nih.gov)
Selective image segmentation has been proposed to address this issue by letting a DNN model process instances with high confidence while referring difficult ones with high uncertainty to experienced radiologists. (midl.io)

With the patient on the system table, 6.1 mCi (226.4 MBq) of 18 F FDG was intravenously administered and was immediately followed by a six-minute, single-bed, list-mode (LM) acquisition centered over the heart, in which an image-derived arterial input function-used as a non-invasive alternative to arterial blood sampling-was generated. (siemens-healthineers.com)
Arterial input functions-derived from the initial single-bed list-mode acquisition over the heart, along with sequential whole-body dynamic acquisitions-were used to generate Patlak-plot-based parametric images reflecting the metabolic rate (MR FDG ) of 18 F FDG as well as the distribution volume (DV).
