Radiology

All About Children

Unlike other facilities in South Texas, our Radiology Department’s physicians and staff focus on children’s imaging 100 percent of the time using X-Rays, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound and other methods. Our pediatric radiologists diagnose many illnesses that do not occur in adults and are specific to children.

Imaging and Radiation

Ionizing radiation can be harmful if the dosage is too high. The pediatric radiologists and technologists at Driscoll adjust the ionizing radiation dose to a level that is as low as possible while still creating an image that allows them to make a diagnosis. This downward radiation adjustment is significantly less than the typical scanning parameters for an adult patient.

Modern Diagnostic Technology

Computed tomography (CT) scanning: Driscoll’s high-speed CT scanners reduce scan-time and the possible need for sedation. The images are captured by a CT technologist and interpreted by a pediatric radiologist who is available for consultation. Helping minimize radiation exposure is our newest piece of equipment, the GE 64-slice CT scanner. For more information on CT scan and preparations for the study, visit our CT Scan section.

Magnetic resonance imaging (MRI): Driscoll’s 1.5T (Tesla) machine provides detailed images for our pediatric radiologist to read and interpret. Capturing good images can be difficult because the child must lie still for the entire procedure (at least 30 to 60 minutes). Driscoll has a child-friendly environment that helps with this process. For more information on MRI, visit our MRI Scan section.

Fluoroscopy: Driscoll has two rooms designated for fluoroscopy, a procedure that captures real-time images of body parts. Using fluoroscopy, contrast agents can be seen traveling through the body, allowing the pediatric radiologist to evaluate internal body functions. For information on specific exams, view our Upper GI sectionContrast Enema X-ray section and VCUG section.

Nuclear medicine: A gamma camera is used to record low-dose radioactive material that is placed inside the patient’s body. These procedures can be performed safely and provide important medical information to your doctor. For more information on nuclear medicine, visit our Nuclear Medicine Scan section.

Ultrasound: Two advanced machines use sound waves to produce medical images. This procedure is preferred for children when possible because it does not involve ionizing radiation. For more information on ultrasound and preparations for the study, visit our Ultrasound section.

X-rays: Diagnostic X-rays using advanced technology are helping Driscoll’s pediatric radiologists diagnose and treat more patients than ever before. For information on specific exams, visit our X-ray section and IVP section.
