  • From a hospital light box, we see a detail of a Magnetic Resonance Imaging (MRI) scan. Sections of a patient's skull and brain illustrate to doctors, potential abnormalities. Dyes used in X-ray and CT scans in the same way because both areas use X-rays (ionizing radiation). Agents work by blocking the X-ray photons from passing through the area where they locate and reach the X-ray film. This results in differing levels of density on the X-ray/CT film but the dyes have no direct physiologic impact on the tissue in the body. MRI contrast works by altering the local magnetic field in the tissue being examined. Normal and abnormal tissue will respond differently to this slight alteration, yielding differing signals. Varied signals are transferred to the images, visualizing many different types of tissue abnormalities and diseases.

  • Lifeguards in the seaside resort of Lowestoft practise the recovery position and resuscitation to a volunteer seaside victim. Lying on the smooth sand near the water's edge, a young man wearing a wetsuit lies pretending to be unconscious, having ingested sea water and requiring immediate treatment by the staff, well-versed in saving lives. As one starts chest compressions, the other holds on the mouth before continuing mouth-to-mouth. Passing time is vital if they are to start a heart and get air into the brain.

  • A memorial to a soldier named Gary Golbey wreaths lie after Remembrance Sunday at the Cenotaph in London's Whitehall, on 12th November 2019, in London, England. A Gulf War veteran who developed a brain tumour but went back on active service had died, aged 42. Colour Sergeant Gary Golbey, originally from Kidsgrove, was taken ill in 2005 when he was part way through his second tour of service in Iraq. But he fought back from his illness to return to the army while in remission. The champion Army boxer spent more than two decades with the Staffords – now 3 Mercian – and saw active service in Northern Ireland, Bosnia and Iraq, where he completed two tours of duty.
