Diagnostic Imaging & Radiology


Our Approach to Treatment

Houston Methodist’s board-certified radiologists use the newest imaging technologies to provide patients the most accurate diagnoses, recommend the best possible treatments and administer minimally invasive therapies. We offer 13 convenient imaging locations across the Greater Houston area to serve you near your home or office.

Our Imaging Services

Computed tomography (CT)

Computed tomography (CT) involves moving an X-ray around a patient to produce multiple detailed images from different angles.


A CT scan provides greater detail of:

Interventional Radiology

Interventional radiologists use imaging to perform minimally invasive procedures and treatments.


The common interventional procedures performed (and conditions treated) include:

  • Arterial interventions
  • Body interventions
  • Cancer therapies and interventional oncology
  • Interventional pain and spine procedures
  • Venous access and treatment
  • Women's health procedures

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI) uses magnets and radio waves to produce images of organs and structures in order to:


A mammogram is a breast X-ray that can show small, early stage cancers.


We offer the following screenings:

  • 3D screening mammogram 
  • Diagnostic mammogram
  • Bone density scan


A physician order for your screening mammogram is not required.

Nuclear Medicine

Nuclear medicine uses small amounts of radioactive materials to examine organ function and structure.


Positron emission tomography (PET) is a type of nuclear medicine that uses radioactive materials, a special camera and computer to evaluate organ and tissue functions. Tests include:

  • Bone scan – diagnoses bone diseases, infections or injuries
  • Brain scan  evaluates brain disorders such as Alzheimer’s disease, seizures, tumors and strokes 
  • Hepatobiliary scan – identifies gallbladder disorders and bile duct obstructions
  • Lung ventilation and perfusion scan (VQ scan) – measures air and blood flow in and out of the lungs
  • Lymphoscintigraphy – evaluates the lymphatic system and identifies lymph nodes for removal
  • Octreoscan – whole-body scans that identify rare neuroendocrine tumors
  • Renal scan – evaluates kidney blood flow and function
  • Parathyroid scan – identifies abnormal parathyroid glands that cause hyperparathyroidism
  • I-131 whole body scan – detects thyroid cancer spread


Ultrasound uses sound waves to produce images of soft tissues inside the body. Types include:

  • Abdominal ultrasound — detects gallstones or tumors
  • Aortic duplex exam
  • Arteriography and venography —diagnose blood flow abnormalities
  • Breast ultrasound
  • Carotid ultrasound
  • Doppler ultrasound
  • Echocardiogram
  • Intravascular ultrasound (IVU) — enables radiologists tsee the inner wall of blood vessels
  • Musculoskeletal ultrasound — examines joints or muscles
  • Obstetrical ultrasound — monitors fetus development
  • Pelvic ultrasound — identifies tumors or masses
  • Peripheral vascular ultrasound — diagnoses vascular conditions
  • Prostate ultrasound — examines nodules
  • Renal ultrasound — examines the kidneys and urinary tract
  • Scrotal ultrasound — examines the testicles
  • Thyroid ultrasound — examines the thyroid
  • Transcranial Doppler (TCD)
  • Vascular ultrasound


X-ray uses a small dose of radiation to produce images of body structures. Types include:

  • Barium X-ray – diagnoses conditions such as tumors, polyps, hernias, strictures, ulcers and other gastrointestinal inflammatory conditions in the GI tract
  • Bone density scan
  • Fluoroscopy  studies movement of internal body parts and systems such as blood flow through a blood vessel or food passing through the stomach and intestines

Other Imaging Specialties

We also offer:

  • Angiography – uses X-rays and a contrast dye to visualize arteries
  • Barium X-ray – an X-ray used to visualize the gastrointestinal (GI) tract
  • Bone density testing – uses X-rays to determine if you have osteoporosis
  • Echocardiogram – also known as a cardiac ultrasound or echo, an echocardiogram uses sound waves to create pictures of your heart
  • Fluoroscopy – a continuous X-ray used to visualize an organ or body part
  • Myelogram – uses X-rays (or CT) and a contrast dye to visualize the spinal canal
