MRI uses a strong magnet and radio waves, with no ionising radiation, to picture soft tissue in finer contrast than CT, so it is the standard scan for brain tumours, prostate, rectal cancer staging, liver lesions and breast screening in high-risk women. It is slow, expensive and blurred by movement.
Superior soft-tissue contrast makes MRI the standard for brain tumours, prostate (multiparametric MRI with PI-RADS), rectal cancer staging, liver lesions, breast screening in high-risk women, and bone marrow. Diffusion-weighted imaging adds cellularity information. Whole-body MRI is used in myeloma and for radiation-free surveillance.
Proton spin alignment in a strong magnetic field; radiofrequency excitation and relaxation times (T1, T2) encode tissue properties. Gadolinium contrast shows perfusion.

Young adults with a grade 2 IDH-mutant glioma who have had surgery can now take a daily tablet that slows or reverses tumour growth and defers radiotherapy and chemotherapy, both of which carry long-term cognitive costs, by years. It confirms that the IDH mutation is a driver that can be targeted, not just a marker. Whether it improves survival or cognition over the long term, and whether it helps in higher-grade or previously treated tumours, is unknown.
Cercek's dostarlimab study is the clearest demonstration that immunotherapy can replace surgery in a solid tumour: patients with dMMR rectal cancer can keep their rectum and avoid the permanent effects of pelvic radiotherapy and surgery. Non-operative management after PD-1 blockade is now in guidelines for this group, and MMR testing before treatment of rectal cancer is essential. The approach applies only to the 5-10% of rectal cancers that are dMMR.
Organ preservation became a plan rather than an accident: consolidation chemotherapy after chemoradiotherapy gives the best chance of keeping the rectum, and salvage surgery after regrowth does not appear to cost survival.
The stage shift the pancreatic cancer page quotes (about three in four surveillance-detected cancers at stage I) and the strongest argument for offering surveillance to every germline carrier found by universal testing, which the NHS does not yet do outside research.
The first total neoadjuvant therapy trial to change practice in high-risk rectal cancer, and the schedule that makes organ preservation possible by giving the tumour months rather than weeks to respond.
The rulebook behind the CAPS cohorts and the UK EUROPAC programme; it is also the reason surveillance for carriers is not yet a routine NHS service, because the consortium itself asked for it to stay within research until benefit was shown.
The limit of what a prostate scan can be asked to do. It is a good triage test for whether to biopsy and a poor map of where every tumour is, which matters for anyone being offered treatment to part of the gland or follow-up by imaging alone.
A scoring tool that needs no new test and can run in primary care records; it turns the 1 percent of Chari's cohort into a 3.6 percent group in whom imaging or a blood test becomes defensible.
