A CT Scan uses computerized multiple X-ray beams. This helps physicians diagnose and treat medical conditions that may not be visible on other types of studies.
A CT Scanner is a ring shaped machine (the ring shape is known as the gantry) that uses advanced x-ray technology to take multiple, high quality pictures of the inside of your body. Immediately after it scans your body, a computer in the scanner reconstructs the data into cross-sectional pictures of your body.
These high quality images allows radiologists to see more detail of brain, bone and soft tissue than they would on a regular x-ray. It also provides your physician with more information to diagnose and plan the treatment for your medical condition.
CT angiography reconstructs the blood vessels to diagnose aneurysms and occlusions.
An MRI scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The scanner is able to produce images that provide detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. Detailed MR images allow physicians to better evaluate various parts of the body and determine the presence of certain diseases.
MRI scans are commonly used to visualize problems of the brain and spinal cord. Other popular applications include tumor diagnosis and problems of the abdominal organs, vascular system, bones and joints.
X-rays are a form of radiation and is part of the electromagnetic spectrum that includes visible light, radiowaves and microwaves.
An x-ray "beam" is used to produce images of various parts of the body. The X-ray beam penetrates through the body and creates an image or picture of the inside of your body.
These images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white. Fat and other soft tissues absorb less, and look gray. Air absorbs the least, so lungs look black.
X-ray imaging is useful to diagnose disease and injury such as pneumonia, heart failure, fractures, bone infections, arthritis, cancer, blockage of the bowel, and collapsed lung, etc.
ULTRASOUND AND COLOUR DOPPLER ULTRASOUND
Ultrasound is a simple, safe and painless diagnostic procedure that bounces high-frequency sound waves off parts of the body and captures the returning "echoes" as images of the inside of the body.
Ultrasound images are captured in real-time, therefore they show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels.
A Doppler ultrasound study may be part of an ultrasound examination. Doppler Ultrasound is a special ultrasound technique that evaluates blood as it flows through a blood vessel.
A Colour Doppler uses a computer to convert Doppler measurements into various colours to visualize the speed and direction of blood flow through a blood vessel.
Bone Densitometry is a simple, non-invasive and painless exam to measure bone mineral density, the mineral content of your bones. It provides information about bone strength or fragility.
During the exam, a machine sends a thin, invisible beam of low-dose X-rays with two distinct energy peaks through the bones being examined. One peak is absorbed mainly by soft tissue and the other by bone. The soft tissue amount can be subtracted from the total, and the difference is the patient's bone mineral density.
This scan is most often used to diagnose osteoporosis, a condition that involves a gradual loss of calcium, causing the bones to become thinner, more fragile and more likely to break.
PACS (PICTURE ARCHIVING AND COMMUNICATION SYSTEM)
Worcester Radiology is a fully digital filmless practice. All our images are stored on our PACS server.
PACS ( Picture Archiving and Communication System) is a computerized means of replacing the role of conventional radiological film.
The images we acquire are digitally transmitted and displayed to referring doctors or the hospital we service. A detailed radiological report is attached to the images. Your physician can thus view your images and read the Radiologist's report.
By making use of the PACS system we ensure that once an image is acquired, it cannot be lost or misfiled.
Interventional Radiology is the subspecialty of Radiology that uses imaging equipment to guide the physician in carrying out a diagnostic or therapeutic procedure on a patient. Areas of the body are accessed through minimally invasive techniques using imaging guidance. X-ray, ultrasound and CT scans are used to guide the movement of instruments within the body during the procedures.
Fluoroscopy is a real time study of the movement of body structures. A continuous X-ray beam is passed through the body part being examined. The beam is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail. The fluoroscope is a flat table with a camera that pulls over the patient and creates a tunnel. The radiologist or technologist will move the camera up and down to best see the area being examined.
Fluoroscopy, as an imaging tool, enables physicians to look at many body systems, including the skeletal, digestive, urinary, respiratory, and reproductive systems.
Mammography has been the most common imaging tool used in the detection of breast cancer for over forty years.
DIGITAL MAMMOGRAPHY is a x-ray technique wich uses low dose x-rays for imaging of the breasts. Computers and specially designed digital detectors are used to produce images that are displayed on a high-resolution computer monitor and stored like other computer files.
Screening digital mammography - is for women who have no signs or symptoms that are suggestive of breast cancer.
Diagnostic digital mammography - is used for patients who have symptoms for instance a palable mass.
Ultrasound - is used in many cases as an additional examination to determine the nature of abnormalities detected on mammography, or for added information in woman with dense breast tissue.
There is no evidence that mammography itself is dangerous or can lead to cancer.
The recommendation is that all women over the age of 40 years should have a regular mammogram: From age 40 to 50 years every 2 years and from age 50 years, annually.
