Our Approach to Treatment

Houston Methodist offers patients advanced imaging and radiology services and technologies. Our board-certified radiologists have access to a range of diagnostic imaging and radiology services, including:

Computed Tomography (CT)

Computed tomography (CT) — moves an X-ray around a patient to produce multiple detailed images from different angles. CT provides greater detail of:


Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI) — uses high-powered magnets and radiwaves tproduce images of organs and structures to:



Nuclear Medicine

Nuclear medicine — uses small amounts of radioactive materials texamine organ function and structure. Positron emission tomography (PET) is a type of nuclear medicine that uses radioactive materials, a special camera and computer tevaluate 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

Ultrasound — uses sound waves tproduce 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

X-ray — uses a small dose of radiation tproduce 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 (http://www.houstonmethodist.org/womens-services/osteoporosis/)
  • 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
