Computed Tomography (CT or “CAT” Scan)

Computed Tomography (CT or “CAT” Scan) scanning is a rapid, painless diagnostic examination that combines x-rays and computers. A CT scan allows the radiologist to see the location, nature, and extent of many different diseases or abnormalities inside your body.

CT scanning can be used to obtain information about almost any body organ (such as the liver, pancreas, intestines, kidneys, adrenal glands, lungs, and heart), blood vessels, the abdominal cavity, bones, and the spinal cord. Our centers have multi-slice, helical CT scanners which generate data and detail quickly and accurately.

 Studies Performed:
  • Abdomen/ Pelvis
  • Sinuses
  • Chest
  • Temporal Bones
  • Head/Soft Tissue Orbits
  • Head/ Brain
  • Spine – Cervical, Thoracic and Lumbar
  • CTA
Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging is an advanced, medically established diagnostic study that utilizes a strong magnetic field and radio waves to produce very sharp images of your body.

MRI scans typically take 15-45 minutes. Detailed studies may take longer. Please refrain from wearing any jewelry. Patients with aneurysm clips or pacemakers may not have an MRI. When making an appointment, we will ask you some additional screening information to ensure your safety.  If requested, we can produce exam images on either CD or film.

 Studies Performed:
  • Abdomen/ Pelvis
  • MRCP
  • Brain
  • Shoulder
  • Spine – Cervical, Thoracic and Lumbar
  • Toe, Ankle & Foot
  • Hand/ Fingers
  • Wrist/ Elbow
  • Knee

Mammography, also known as a mammogram, is the examination of the breast using x-rays. Mammography is considered the most effective tool for early breast tumor detection. Most medical experts agree that successful treatment of breast cancer often is linked to early diagnosis. Mammography plays a central part in early detection of breast cancers because it can show changes in the breast up to two years before a patient or physician can feel them.

Digital Mammography allows the radiologist to alter the orientation, magnification, brightness and contrast to produce images of the breast that can be seen on a computer screen. It reduces the time of the examination compared to non digital (analog) mammograms. Digital Mammography has been shown to be superior to traditional analog mammography in women with dense breast tissue.


What is Ultrasound?

Ultrasound (sonography) is a procedure that uses sound waves to create images of internal organs. The reflecting sound waves (echoes) are recorded and displayed as visual images. Because ultrasound images are captured in real time, they can show movement, like blood flow, heart beats and baby movement.

 Studies Performed:
  • Abdomen & Pelvis
  • Aorta
  • Breast
  • DVT Study
  • Breast Core Biopsy
  • Follicle Study
  • Pregnancy
  • Scrotal
  • Appendix
  • Biophysical Profile
  • Carotid
  • Thyroid Fine Needle Aspiration/Biopsy
  • Drainage of certain fluid collections
  • Obstetrics
  • Renal
  • Thyroid

Pediatric Studies:
  • Hips
  • Neonatal
  • Pylorus
  • Sacrum

What is X-ray?

X-ray is the oldest and most frequently used form of medical imaging. X-rays can produce diagnostic images of the human body on film or digitally on a computer screen. At AVISENA we utilize  a CR system (computerized radiography), which processes and stores the x-rays as a digital image. X-ray imaging is the fastest and easiest way for a physician to view and access the lungs, broken bones, joints or spinal injuries. At least two images (from different angles) are taken and often three images are needed if the problem is around a joint (knee, elbow or wrist).

Studies performed but not limited to:
  • Abdomen
  • Series/KUB
  • Ankle
  • Chest
  • Elbow
  • Femur
  • Hand
  • Heel
  • Wrist
  • Knee
  • Finger/ Thumb
  • Scolios
  • Shoulder
  • Sinuses
  • Forearm
  • Foot
  • Pelvis

Radiographic examination requires our patients to follow a certain guidelines as follows:

For examination involving the use of x-rays kindly ensures:

  • The part for x-ray is free of metal objects, e.g zippers, buttons Or jewellery, for this reason you may be asked to change in to a hospital gown.
  • Ladies undergoing Mammogram are advised against putting on talcum, perfume or deodorant on the day of your appointment.

For MRI examination:

  • The devices/conditions listed below might prohibit you from having an MRI examination. If you have any of these devices, make sure your physician and the MRI staff are informed. If you have any doubts or questions, be sure to ask.
    • Pacemakers
    • Artificial heart valves
    • Neuro-stimulators
    • Metallic clips used in brain surgery
    • Implanted hearing aids
    • Metal implants
    • Metal shrapnel in your body
    • Metal fragments in your eyes
    • Intra-uterine contraceptives devices
    • Claustrophobia
Low Dose Chest CT

What is CT Scanning of the Chest?

CT images of internal organs, bones, soft tissue and blood vessels typically provide greater detail than traditional x-rays, particularly of soft tissues and blood vessels. Low dose chest CT is currently used clinically for detecting lung cancer and following some lung nodules.

Chest CT can demonstrate various lung disorders, such as:

  • Lung cancer
  • Pneumonia
  • Tuberculosis
  • Emphysema and obstructive lung disease (COPD)
  • Bronchiectasis
  • Inflammation or other diseases of the pleura, the covering of the lungs.
  • Diffuse interstitial lung disease
  • Congenital abnormalities.


  • CT scanning is painless, noninvasive and accurate.
  • Unlike conventional x-rays, CT scanning provides very detailed images of many types of tissue as well as the lungs, bones, and blood vessels.
CT Colonoscopy

What is CT Colonoscopy?

Most colon cancers develop from polyps, which are abnormal growths in the colon. If polyps grow unnoticed and are not removed, they may become cancerous.

CT Colonoscopy is an advanced method to screen for colon cancer and polyps in a non-invasive way which is safer and is more comfortable for more patients. This method which produce a virtual ‘3D fly-through’ movie of the colon does not require you to be sedated or undergo anaesthesia.

Who is considered High Risk?

  • Personal history of colon cancer or colon polyps
  • A strong family history of the disease
  • Inherited forms of colon polyps or cancer
  • Predisposing chronic digestive condition such as inflammatory bowel disease (Crohn’s disease or ulcerative colitis)
  • Recommended for average risk individuals beginning at age 50

What happens during a CT Colonoscopy? The Radiologist will explain the procedure and will let patient know of any issues with bowel preparation.

  • The examination takes 15 to 20 minutes.
  • You will be asked to lie on the scanner.
  • You may have a cannula (tube) inserted into one of your arm veins
  • The Radiologist inserts a short catheter into the rectum.
  • A muscle relaxant may be injected to avoid bowel spasm.
  • You may be given intravenous contrast through the cannula.
  • Air is introduced via the tube into your bowel.
  • This is done in a controlled manner via a specially designed pump.
  • It is normal to feel some bloating and mild discomfort.
  • There is sufficient air then the Radiologist take images through the entire bowel.
  • You will be asked to lie in different positions to distribute the air before taking the images.
  • The Radiologist will analyze the pictures via special software.

Benefits of CT Colonoscopy

  • Minimally invasive test provides three dimensional images
  • Lower risk of perforating the colon than conventional colonoscopy.
  • Good at detecting polyps larger than 1 centimeter in size
  • An excellent alternative for patients who have clinical factors that increase the risk of complications from colonoscopy, such as treatment with blood thinners or severe breathing problems.
  • Does not require any sedation
  • Less costly than a colonoscopy
  • A better option for elderly patients, especially those who are frail or ill


The HSG test is a radiology procedure usually done in the radiology department of a hospital or outpatient radiology facility. This shows whether the fallopian tubes are open or blocked and whether a blockage is at the junction of the tube and uterus (proximal) or at the other end of the tube (distal).

What is the use of HYSTREROSALPHINGOGRAM (HSG)  test?

Hysterosalpingography, also called uterosalpingography, is an x-ray examination of a woman’s uterus and fallopian tubes that uses a special form of x-ray called fluoroscopy and a contrast material. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

How long does a HYSTREROSALPHINGOGRAM (HSG) test take?

While the actual procedure takes about five minutes, you should plan to arrive for your HSG 30 minutes prior to your scheduled appointment. You can also expect to be with us for 30-45 minutes after the scheduled HSG start time.


The Radiologist will explain the procedure and will let patient know of any issues with bowel preparation.

  • Appointment is set either on 9th,10th or 11th day from the onset of menstruation.
  • No sexual intercourse until the examination is completed.
  • Please bring one (1) sanitary pad  on the day of examination.
  • No fasting required.
  • Some bleeding from the vagina (like menses) can be expected. However, should the bleeding be profuse, you must go and see you doctor.
  • Some patients experience some lower abdominal pain or discomfort. Should these become severe or persist, you must go and see your doctor.
