About

Dr Alex Horton is a Consultant Radiologist at the Royal Surrey County Hospital, trained in cross-sectional and interventional radiology. In his NHS role he is lead radiologist for transarterial chemoembolisation (TACE) and selective internal radiation therapy (SIRT) for liver cancer, and radiology lead for hepatocellular carcinoma, pancreatitis, and prostate and bladder cancer. He is a core member of the hepatobiliary multidisciplinary team and has served as an expert adviser to the NICE pancreatitis guideline committee.

He provides multiparametric (diffusion) MRI of the prostate for the non-invasive diagnosis of prostate cancer, and his vascular interests include CT and MR peripheral angiography, CT coronary angiography and calcium scoring.

Dr Horton is a college tutor for radiology trainees in Kent, Surrey and Sussex, an FRCR examiner, and teaches at the University of Surrey medical school.
