X-rays or radiographs, are a type of diagnostic procedure that uses electromagnetic waves to capture images within the structures of the body. An X-ray image consists of a combination of black and white shades resulting from different tissue absorptions of radiation. Bones appear white due to their calcium content, while soft tissues, like fat, absorb fewer X-rays, appearing grey. Lungs appear black because air absorbs the least radiation.
Pre-procedure: The patient will be instructed to remove any metal objects, clothing, or jewellery that interfere with the procedure. Inform our specialist if you are pregnant. Moreover, a gown is provided during the procedure in case you are told to remove any clothing for better access to the area being examined.
Procedure: Depending on the type of X-ray being taken, patients will be guided to different positions, such as lying down, sitting, or standing, as instructed. X-ray beams are passed through the body, and images are captured. A lead apron is used to shield parts of the body from unnecessary radiation exposure.
Post-procedure: After the procedure, you will be given your clothing and personal belongings. The radiologist will interpret your scan and send it to your specialist.
The time duration for an X-ray procedure is based on the type of procedure performed and the region for assessment. Contrast radiography usually takes an hour or more for evaluation. Except for spine X-rays, which may take 30–45 minutes, all other exams, including chest X-rays span between 15 and 30 minutes.
X-rays employ ionising radiation in safe doses to generate images of the body. However, there are risks associated with X-rays, which include:
The probability of developing cancer within 10 years of the procedure taken, although less.
Children are susceptible to the effects of X-ray radiation compared to adults.
Rarely, dye used in contrast radiography may cause severe reactions, such as anaphylactic shock, hypotension, and cardiac arrest.
X-ray radiation might affect the foetus of pregnant women, hence, they can opt for an ultrasound.
X-ray procedures help medical specialists to:
Diagnose various fractures that occur in bone
Locate bone dislocations or misalignments
Insert central venous access devices, such as PICC lines (CVAD)
Perform response assessment scan in breast cancers
Address respiratory cardiac, gastrointestinal, and bone-related ailments such as blocked blood vessels, pneumonia, emphysema, digestive problems, and fractures
Determine foreign objects inside the body, such as coins or metal fragments.
Contrast radiography involves using contrast dyes such as iodine or barium and being examined using X-ray fluorescence. It is generally used to address ailments such as tumours of both benign and malignant origin, ulcers, stones, and the completion of post-operative evaluations. Contrast dyes are generally administered orally, intravenously, or through the rectum. Side effects of contrast radiography generally include an unpleasant taste due to the intake of dye, burping, or a mild burning sensation in the face, neck, and genital region.
X-ray procedure is a preferred diagnostic imaging scan for medical professionals to visualise the internal structures of the body. Alternatives to X-ray procedures that are available at our hospital include:
Ultrasound: The procedure involves using sound waves to create images of tissues, organs, and bones.
Magnetic resonance imaging scan (MRI): The procedure uses a combination of magnetic field and computer-generated radio waves to create detailed images of structures within the body.
Computed tomography scan (CT): The procedure involves using X-rays and different angles and computers to create three-dimensional, cross-sectional images of bones, soft tissues, and blood vessels within the body.
Bone-density test: Also called dual X-ray absorptiometry (DEXA) scan, the procedure involves using X-rays to measure the thickness and strength of bone.
Fluoroscopy: The procedure employs continuous X-ray beams at the target region, enabling medical professionals to generate and monitor live images of internal body structures.
Movement during X-ray images will affect the accuracy, creating distorted images, and making it tough for your medical healthcare provider to provide an accurate diagnosis. It is essential to follow your radiologist’s instructions during the procedure to get an exact reason for your ailments and treatment plan.
There are no specific restrictions on performing normal activities after taking an X-ray. In case you are subjected to contrast radiography, our specialist will advise you to consume a lot of water to flush out the contrast.
Portable or Mobile X-rays are used mainly for bedridden patients, and for those patients who cannot come to the procedure room. Advancements are being made to address bedridden patients, such as Ceiling Suspended Full Room Digital Radiology, where X-ray systems are hung on the ceiling, and are moved around with the aid of motors and detectors to get the best angle of images.
Your radiologist will analyse your scan and interpret the findings, which will then be sent to your medical healthcare provider. Normally, it would take one to two days for you to receive your results. For critical care patients, results are provided immediately to provide timely assistance. Your medical healthcare provider will schedule a follow-up appointment post-procedure to discuss your results and guide you through the next course of action.
