PI-RADS v2 is designed to improve detection, characterization and risk stratification in patients suspected of prostate cancer with a goal of better treatment decisions, improved outcomes and simplified reporting. However, multi-center validation trials are needed and expected to lead to modifications in the scoring system. [11]
The Cancer Imaging Archive (TCIA) is an open-access database of medical images for cancer research. The site is funded by the National Cancer Institute's (NCI) Cancer Imaging Program, and the contract is operated by the University of Arkansas for Medical Sciences. Data within the archive is organized into collections which typically share a ...
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
Removing the final step – which involves patients being injected with contrast dye – could slash costs and time, as well an increasing availability.
The technique has demonstrated higher accuracy than other modalities in assessing seminal vesicle invasion and extra-capsular extension (ECE) of prostate cancer (96% and 81% respectively). Endorectal coil MRI is useful for determining the extent of spread and local invasion of cancers of the prostate, rectum, and anus. [2]
1990s – Treatment of bone and kidney tumors by embolization. 1990s – RFA for soft tissue tumors, i.e., bone, breast, kidney, lung and liver cancer. 1997 – Intra-arterial delivery of tumor-killing viruses and gene therapy vectors to the liver. 1997 – HIFU first used to treat prostate cancer.
For example, imaging of prostate tumors is better accomplished using T2-MRI and DWI-MRI than T2-weighted imaging alone. [7] The number of applications of mpMRI for detecting disease in various organs continues to expand, including liver studies, breast tumors , pancreatic tumors , and assessing the effects of vascular disruption agents on ...
For example, in the context of oncology, an MRI scan may reveal the shape and size of a tumor, while an MRSI study provides additional information about the metabolic activity occurring in the tumor. MRSI can be performed on a standard MRI scanner, and the patient experience is the same for MRSI as for MRI.
