A diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce cross-sectional images (often called slices) of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles and organs and may be performed to aide in a patient’s diagnosis. Tumors, internal bleeding and internal injuries may be better visualized through the use of CT. We offer the following CT scans:

• Low-dose CT scans – 64 slice, 96 slice, 256 slice

Magnetic Resonance Imaging (MRI) uses magnetic fields and radio frequencies to produce detailed pictures of organs, soft tissues and bones. Unlike X-rays or CT scans, MRIs do not use ionizing radiation. We offer the following best-in-class MRI machines:

• 3 Tesla MRI
• 3 Tesla Wide-Bore MRI
• 1.5 Tesla Wide-Bore MRI

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 (DEXA)

In most cases, you do not need a referral for a screening mammogram. Learn more about the Houston Methodist Breast Care Center at The Woodlands.

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 a computer to evaluate organ and tissue functions. Our PET/CT uses innovative software to produce highly accurate scans rapidly, a critical advantage because longer scans increase the chance of patient movement that can interfere with image quality. The table moves in a single continuous motion through the scan, which reduces patient movement compared to the stop-and-start motion of traditional scanners. This allows for less exposure to radiation and fewer retakes.

Tests include:

• Bone scan – diagnoses bone diseases, infections or injuries
• Brain scan – evaluates brain disorders such as Alzheimer’s disease, seizures, tumors and strokes
• DaTscan – Single-photon emission computed tomography (SPECT)-brain imaging used to assist in the evaluation of adult patients with suspected Parkinsonian syndromes
• 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

• Angiography
• Bone density/DEXA testing
• Cardiac imaging
• Echocardiogram
• Fluoroscopy
• Interventional radiology
• Myelogram
• Ultrasound
• X-ray
