X-rays are a useful tool for diagnosing certain health conditions and diseases. Your doctor may refer you for an x-ray to check for broken bones, pneumonia or cancer, or your dentist will use x-rays to look inside your teeth for potential problems such as dental cavities. A radiologist or pathologist studies the results of x-rays, and a letter will be sent back to your doctor. You will often be asked to take the x-ray films with you.
A medical centre is an establishment housing a group of doctors offering healthcare services from a single premises. Medical centres differ in size and type. Some may offer doctors in general practice or another area such as plastic surgery, oncology, radiology, dermatology, gastroenterology etc., or a combination of both general practitioners and specialists. Public hospitals will often have a medical centre close nearby, where doctors from these public hospitals can also see patients privately. These doctors are known as specialists, for example cardiologists and surgeons.
Pathology is the study of the causes and effects of disease by looking at cells, fluids and tissues from your body. It is a critical part of medicine, and all medical students will study pathology before becoming a doctor. A pathology centre is where your general practitioner (GP) or specialist doctor can send samples or specimens from your body for analysis to help in the accurate diagnosis of your condition or disease. To summarise, there are five main sample and specimens which your GP may take or send in to a pathology centre.
A Magnetic Resonance Imaging (MRI) scanner is a device linked to a computer which generates a 3-D image of an area of your body. Unlike X-rays and CT scans, there is no ionizing radiation with an MRI, and therefore it is supposedly without risk. MRIs also provide more accurate pictures of the differing soft tissues within your body. This is particularly useful if your doctor wants to look at the brain, the heart, muscles and cancers, but it can be used for any part of your body.
