Computed Tomography Angiography (CTA)
Definition
Computed tomography angiography (CTA) is a non-invasive diagnostic imaging procedure that uses X-ray technology and computer processing to create detailed images of blood vessels and surrounding tissues. It helps in the evaluation, diagnosis, and treatment planning of vascular conditions, such as aneurysms, blockages, and malformations.

Abdominal Imaging
The breadth of experience among our doctors is reflected in their unique approach to patient care, management of complex medical cases, expertise in imaging guidelines and unwavering commitment to clinical excellence. Magnetic resonance imaging (MRI) is a noninvasive medical test that physicians use to diagnose and treat medical conditions. It uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. An MRI does not use radiation. A computed tomography scan, more commonly known as a CT scan, is a diagnostic medical test that produces multiple images of the inside of the body. The cross-sectional images generated during a CT scan can be reformatted in multiple planes, and can even generate three-dimensional images of internal body structures. We also specialize in fluoroscopic imaging—real-time moving pictures displayed on a monitor. This specialized technology helps us detect conditions that affect the gastrointestinal as well as the urinary and reproductive (genitourinary) tracts. Our experts perform esophagrams, upper GI series and barium enemas to look for swallowing and digestion conditions. In addition, we do a variety of other imaging tests, including cystograms to detect voiding issues and hysterosalpingograms, which help us see if a woman’s fallopian tubes are open or blocked.Cardiac Advanced Imaging Program
Capturing and interpreting images of the heart are essential to successfully managing cardiac conditions. Our program features advanced technology to capture images of the heart, which allows our physicians to make accurate diagnoses and determine the best course of treatment. Among the techniques we use are nuclear cardiology, echocardiography, and cardiac CT (computed tomography) imaging, a diagnostic method that allows us to take images of blood vessels, bones, and internal organs. Our nuclear cardiology laboratories offer such state-of-the-art imaging techniques as single-photon emission computed tomography (SPECT), positron emission tomography (PET), and SPECT-CT, and our team has a long history of groundbreaking research in cardiovascular nuclear imaging. Our echocardiography (ultrasound) laboratories provide a comprehensive array of 2-D and 3-D transthoracic (chest wall) and transesophageal (through the esophagus) imaging options, as well as intracardiac echo imaging (ICE), an imaging technique that allows physicians to get a clear picture of the inner workings of the heart.Interventional Radiology
The Yale Medicine Interventional Radiology (IR) program is one of the leading programs in the nation. Our interventional radiologists, recognized as pioneers in the field of minimally invasive medicine, work with nursing and technologist staff to offer image-guided, non-surgical treatments for vascular and non-vascular disease with excellent outcomes for pediatric and adult patients. Our interventional radiology procedures are performed for a broad range of conditions spanning gastrointestinal/hepatobiliary, gynecology, infectious disease, oncology , pediatrics, pain management, urology, and venous and arterial disease. Interventional radiologists use advanced imaging modalities including ultrasound, fluoroscopy, computed tomography, and magnetic resonance imaging to perform procedures through tiny pinholes, thereby avoiding surgery and long recovery times. IR advances enable minimally invasive treatment of many conditions on an outpatient basis, allowing patients to recover in the comfort of their own home. We also offer comprehensive care dedicated to the treatment of pediatric patients, including vascular malformations, biopsy service with sedation, feeding tube maintenance, and expert care in hepatobiliary, urological, gastrointestinal, and musculoskeletal disorders. Our team at Yale New Haven Hospital was the first in Connecticut and among the first in the nation to perform transcatheter pulmonary embolectomy, a procedure for the removal of a blood clot from the pulmonary arteries. Such patients are initially evaluated by a multidisciplinary Pulmonary Embolism Response Team (PERT) , and a comprehensive treatment plan is then developed. We also have one of the world’s leading hereditary hemorrhagic telangiectasia (HHT) and vascular malformation programs. Founded in 1994, both serve as role models for other programs around the world. We offer a wide range of minimally invasive Interventional Radiology treatments, all available at Yale New Haven Hospital.
