CT Modalities

Houston Methodist physicians have access to the latest diagnostic and imaging technologies to accurately identify your condition in order to develop an immediate plan of treatment. Our innovative imaging technology includes the cardiac MRI, the 64-slice cardiac CT, the DynaCT and  3-D echocardiography, along with our new lower dose imaging technologies that include GE Revolution (GE’s low-dose CT scanner), bariatric CT (higher weight capacity), low-dose lung imaging and 256-clice CT technology.   These enable our fellowship-trained, board-certified radiologists  to evaluate a wide range of parts of the body and conditions :

  • Aortic and abdominal aneurysms
  • Blood flow (vascular conditions)
  • Bone injuries (and bone density)
  • Head, neck and spine trauma
  • Heart conditions and cardiovascular disease
  • Internal organs (kidneys, bladder, esophagus, stomach, intestines, colon)
  • Musculoskeletal (muscle and skeletal) disorders
  • Oncological Imaging 
  • Transplant Imaging 
  • Traumatic injuries
  • Tumors

Computed Tomography
Unlike X-rays, computed tomography (CT) allows for imaging full cross-sections of parts of the body. This is especially useful when high detail is necessary, such as in cases of internal injury or cancer detection. Houston Methodist  has dedicated computers  that allow for advanced specialized post-processing for 3-D imaging, ensuring that physicians and patients receive information in a timely manner.

Our CT scanners   have the ability to perform a wide array of imaging procedures:

  • CT angiographic scans
  • CT fluoroscopy
  • CT 3-D imaging
  • CT brain perfusion 

Houston Methodist’s commitment to patient safety is illustrated by our addition of new lower dose imaging technologies:

  • GE Revolution CT  (a CT scan that uses lower doses of radiation using GE’s Smart Dose Technologies)
  • Bariatric CT (higher weight capacity)
  • Low dose lung imaging
  • 256-slice CT technology

Cardiac CT
The rapid, non-invasive cardiac CT allows radiologists to take detailed images of the heart and arteries. This type of scan is used when patients are suffering from symptoms including acute chest pain or when other tests like electrocardiograms or stress tests have uninterpretable results. A cardiac CT helps with diagnosing artery disease, calcium build-up and blockages, aneurysms, masses, physical defects of the heart, heart disease, tears in the aortic wall, blood clots in the lungs, and heart rhythm disorders.    

DynaCT is a potentially life-saving innovation in interventional radiology called angiographic computed tomography (ACT), enabling physicians to see vascular abnormalities and surrounding soft tissue during an angiography procedure, avoiding the time lost having to leave the angiography suite for CT imaging. In emergency situations, such as a ruptured blood vessel, this imaging capability enables more rapid assessments and initiation of treatment.

3-D Echocardiography  
A  3-D echocardiography provides cardiac ultrasound imaging and involves the passing of a probe down the esophagus, using transesophageal echocardiogram (TEE) technology that can produce dynamic, real-time images of the heart in motion . Our board-certified radiologists   have extensive expertise in using 3-D echocardiograms to diagnose various causes of chest pain, breathing difficulties and dysrhythmias, as well as heart and heart valve defects in order to determine the most appropriate interventions.
