Diagnostic tests are some important processes through which medical professionals identify certain diseases and conditions. There are numerous diagnostic tests in medical science, but today, ILS Hospitals would like to highlight a few of them. Let’s know about certain diagnostic tests in brief.
CT (Computed Tomography) Scan
Computed tomography scan or well-known as CT scan is a diagnostic imaging test done by the medical professionals to view the inside of the body. CT scan takes X-ray images from different angles and a computer to generate cross-sectional (tomographic) images of bones, blood vessels, organs and other soft tissues. CT scans are used by the doctor to diagnose-
To determine the method of treatment for operations, biopsies and radiation therapy
To observe the efficacy of treatment, like radiation therapy etc.
MRI (Magnetic Resonance Imaging) Scan
MRI is a diagnostic imaging tool which uses strong magnetic fields and radio waves to produce comprehensive images of the organs in the body. An MRI scan helps in diagnosing conditions, like tumours, injuries in the brain due to trauma, cysts, abnormalities of the brain and spinal cord, heart conditions, stroke and many more.
As MRI scan uses strong magnetic fields, it is not suitable for pregnant women and people with pacemakers, cochlear implants, artificial joint, metal plates, dental fillings, intrauterine device (IUD) and some others.
Electromyography helps in diagnosing the health of your muscle and nerve disorders, like muscular dystrophy, multiple sclerosis, amyotrophic lateral sclerosis (ALS). You’ll be prescribed EMG if you suffer from muscle cramps, numbness, tingling etc. In EMG, the technician will insert electrodes at various parts of the body as per your symptoms. The electrodes will release electrical current at certain times to check for the muscle’s activity, so it can cause a little discomfort to the patient.
Endoscopy is another diagnostic test in which an endoscope, a long and thin flexible tube attached with a light and camera is inserted through the mouth to get detailed images of the digestive system. The gastroenterologist recommends endoscopy to determine certain health-conditions as follows:
Liver function test/s (LFT/s)
Liver function tests are also called hepatic panel and are a collection of blood tests recommended by the doctor to determine the person’s liver health and performance by measuring the proteins, enzymes and bilirubin in the blood as discharged by the liver. This diagnostic test is required to check for inflammation (hepatitis), infection and other diseases in the liver. You are most likely to be recommended LFT by the medical supervisor if you have serious medical conditions like high blood pressure, diabetes, anaemia etc.
Echocardiography is used to monitor the heart’s functioning and defects. In an Echocardiography, sound waves are produced by the machine to create live images (echocardiogram) of the heart. During the test, the Echo technician will attach soft sticky patches (electrodes) on your chest and put gel on a transducer to be pressed on your chest for the examination.
Endoscopy is one of the most employed diagnostic probes that are used in the domain of medical science in the leading hospitals of India, which also includes Kolkata. The term endoscopy literally means to ‘look inside’ and for medical purpose, it rightfully enable the doctor to look inside the body and figure out the probable cause of any discomfort or as a treatment approach for some medical conditions. The technique is very similar to a laparoscopic surgery and is done by inserting a particular kind of instrument into the cavity and hollowed organs.
There are multiple types of the same depending upon the site on the body. Also, the patient may or may not be given a dose of anesthesia, depending upon the procedure. Endoscopy in broader term refers to the procedure, in usage, it is synonymously used for the procedures carried out in the upper gastrointestinal tract, primarily inserted through the nose or mouth.
An endoscopy is a highly efficient procedure to determine the underlying cause of any illness or discomfort without opening it up by making a large incision. Several times, it is also used to extract a few tissues for the site for the purpose of biopsy and other screenings. Though it is a bit rare and executed only when a possible case of cancer or malignancy is suspected. It also proves to be an extremely beneficial tool to determine the effect of any medication and new treatment procedure.
As already mentioned, for upper gastroenterology, the endoscopic probe is mostly inserted through the mouth, nose or rarely through a small cut made on the epidermal layer of the skin. It is stitched back after the completion of the procedure. The endoscopic procedure is almost similar to that of a laparoscopic surgery.
To aid the visuals, the endoscope probe also comprises of a cold light source and camera, which projects the real time image of the internal organ. The internal images can either be decoded and evaluated by the pathologist directly or can be screened and saved, for the respective doctor to analyze it later.
The endoscopy is an extremely popular diagnostic tool in the medical world. It is usually sufficient for determining the underlying cause. After it reveals the primary results, it might lead to either oral medication, drug therapy or surgical approach, depending upon the individual case and type of illness.
