"I spend half my week practising medicine and the other half writing and talking about it as a GP in Gloucestershire. Working on Case Notes has been a boon for both me and my patients. One of the principal aims of the programme is to keep our listeners up-to-date with the latest developments in healthcare, and to accomplish that I get to interview a wide range of specialists at the cutting edge of medicine. A rare privilege that ensures our listeners aren't the only ones to learn something new."

Radiology
In the first of the new series of Case Notes, Dr Mark Porter looks at the role of radiology.
Nowadays medical applications of radiology are widespread, and include diagnosis of disease, radiotherapy and research.
Mark visits Hammersmith Hospital鈥檚 imaging department which offers a wide range of diagnostic and interventional procedures ranging from barium studies and ultrasound to bone density scanning.听
The Hammersmith听was the first hospital in the world to develop PACS 鈥 picture archiving and communication system 鈥 facilitating filmless X-rays and paperless reporting, which听significantly reduce delays to the patient.
What are the effects of exposing patients to radiation? How safe are CT (computerised tomography) scans, which have revolutionised the diagnosis and treatment of diseases affecting almost every part of the body?听
Mark investigates recent concerns about the increasing number of healthy people who are having CT body scans for 鈥渉ealth MOTs鈥, and considers when the long term benefits of screening are greater than the risk of radiation exposure.
He also hears about strategies for dealing with patients who find scanners claustrophobic:听听Open MRI scanners, where the patients aren't enclosed in a small cylinder, are one way around the problem.
And Case Notes examines a new form of brachytherapy, a type of radiotherapy used to treat prostate cancer. Brachytherapy involves planting tiny pellets of radioactive material directly into the prostate gland, maximising the dose to the tumour and minimising damage to the urethra, bladder and rectum. |
