Our radiology service offers a full range of scans and imaging to diagnose and treat diseases for patients. The radiology department provides imaging service 24 hours daily for inpatients, outpatients, and emergency patients of all ages.

Below is a list of some techniques used in the Radiology Department:

  • Computed Tomography (CT scan)
  • General Radiography
  • Mammography
  • Ultrasound
  • Bone Densitometry
  • Digital Portable X-ray / Mobile X-ray 

Computed Tomography (CT)

Computed Tomography (CT) is an advanced X-ray technique that uses computer technology together with x-rays to provide high-resolution 3D images of the internal organs of the body. With these high-resolution 3D images, the radiologist and clinician can make a more precise diagnosis or surgical planning.

CT Coronary Artery Calcium Scan

CT Calcium Scan is a measurement of the calcium deposits in the wall of the coronary arteries. The inflamed deposits in the coronary arteries accumulate calcium, and the score reflects the build-up of plaque or atherosclerosis. The more calcium (and therefore higher score), the higher risk that a person may have a heart attack.

CT Calcium Scan is performed with a CT scanner and is quick to measure. Doctors may recommend proceeding with CT Coronary Angiogram (CTA) if the person has a high score on CT Calcium Scan, as it increases the probability of significant Coronary Artery Disease (CAD).

Estimated completion time: 5 – 15 minutes

Mammography

Mammography is used to examine the breast for the early detection of cancer and other breast diseases.

Estimated completion time: 10 – 15 minutes

CT Coronary Angiogram

CT Coronary Angiogram (CTA) is a non-invasive imaging study of the coronary arteries. This test produces more accurate and good-quality images of the coronary arteries, as well as the presence of calcified and soft plaques in the arteries.

This study can suggest the presence of Coronary Artery Disease (CAD) even when the coronary arteries are less than 50% narrowed or blocked. This allows the doctors to assess the degree of risks that the patient has of CAD.

The procedure is performed on an outpatient basis, and an oral medication (beta-blocker drug) is given to patients that have a high heart rate. Patients are able to resume their daily activities after the examination.

Estimated completion time: 20 – 30 minutes

General X-ray

X-ray has been commonly used for decades. It helps the doctors to give a brief view of what is inside your body. This helps to diagnose and monitor many medical conditions.

Portable X-ray / Mobile X-ray

Portable x-ray or mobile x-ray units are mobile equipment to diagnose and monitor patients where transfer to the hospital radiology department is an obstacle, for example, patients in intensive care units (ICU). These units are equipped with wheels that allow the radiographers to move them to different locations. Mobile x-ray equipment is designed to move within limited spaces between hospital beds.

Estimated completion time: 10 –15 minutes 

Bone Densitometry

Bone densitometry, also called dual-energy x-ray absorptiometry (DEXA) is the gold standard to diagnose osteoporosis. It uses a very small dose of ionizing radiation to produce images of the spine and hips to measure bone loss. DEXA is fast and non-invasive.

Estimated completion time: 10 – 15 minutes

Ultrasound

Ultrasound uses sound waves to create images (also known as sonograms) of structures inside the body such as organs and tissues. In contrast to x-rays, ultrasounds do not use any radiation. It can show the body parts in motion, such as the heart beating or blood flowing through the vessels.

It is able to view and provide information on organs including the heart, blood vessels, liver, bladder, kidneys, thyroid, and female reproductive organs.

Estimated completion time: 25 – 40 minutes
