Our Services

Computed Tomography (CT)

Computed Tomography (CT)

Hours of Operation:
Monday to Friday
7:30 a.m. – 11:00 p.m.

  • CT scans use X-ray to take detailed pictures inside the body.
  • Each rotation of the scanner takes less than a second, and creates a picture of a thin slice of the organ or area of interest.
  • CT can be used to study all parts of the body.
X-ray

General Radiography (X-ray)

Hours of Operation:
Monday to Friday
7:30 a.m. – 5:00 p.m.

  • X-rays are the oldest and most frequently used form of medical imaging.
  • X-rays use small amounts of radiation to produce images of bones and internal organs.
  • It’s non-invasive and helps physicians diagnose and treat medical conditions.
Interventional Radiology

Interventional Radiology

Hours of Operation:
Monday to Friday
8:00 a.m. – 4:00 p.m.

  • Interventional radiology offers some of the most minimally invasive, targeted treatments available.
  • It uses X-rays, Ultrasound, CT and other imaging to advance a catheter in the body.
  • IR treatments allow for lower risk, less pain, and shorter recovery time.
Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging (MRI)

Hours of Operation:
24 hours, 7 days a week

  • MRIs produce pictures of the body using powerful magnets and radio waves.
  • MRI is a non-invasive procedure.
  • Blood flow and organ motion can be measured with MRI
  • Unlike CT or PET scans, MRI does not use radiation to take an image.
Molecular Imaging (Nuclear Medicine)

Molecular Imaging (Nuclear Medicine)

Hours of Operation:
Monday to Friday
8:00 a.m. – 5:00 p.m.

  • Nuclear medicine uses small amounts of radioactive material, called radiopharmaceuticals, to aid diagnosis.
  • The radiopharmaceutical emits energy from the body, which is picked up by a Gamma Camera.
  • It’s safe and typically non-invasive.
Ultrasound

Ultrasound

Hours of Operation:
Monday to Friday
8:00 a.m. – 5:00 p.m.

  • Ultrasound uses sound waves to see the inside of the body in real-time.
  • It allows examination of organs, soft tissues and blood vessels.
  • Common uses include examination of the uterus, liver, thyroid, heart—the list goes on!
