Low Dose CT Scan

Center for Diagnostic Imaging Added Low Dose CT Scanner in Bridgeton

A CT Scanalso called computerized tomography or just CT, is an X-ray technique that produces images of the body that visualize internal structures in cross section rather than the overlapping images typically produced by conventional X-ray exams.

Conventional X-ray exams use a stationary machine to focus beams of radiation on a particular area of the body to produce two-dimensional images on film or a digital detector, much like a photograph. CT scans use a powerful computer and an X-ray unit that rotates around the body. The result is a set of cross-sectional images, like slices, of any part of the body (from the brain to the foot). Contrast agents may be used intravenously or by mouth to see blood vessels, intestines, kidneys or lymph nodes more clearly during a CT.

The new Somatom Perspective 64-slice Multi-Detector CT (MDTC) scanner from Siemens delivers high-quality images with both speed and accuracy, while delivering an ultra low radiation dose, when compared to other scanners.

“To the patient, the lowest possible dose is as critical as high image quality,” said Dr. Steven Rothfarb of CDI. “The Somatom Perspective is based on a proven platform that enables high-end imaging at an extremely low dose, without compromising clinical results.”

Pediatric scanning in particular, is sensitive to a reduced dose, Dr. Rothfarb said, as children are more susceptible to radiation than adults. “Somatom Perspective comes with dedicated modulation curves specifically tailored for these most delicate patients.”

The ultra low dose CT Scanner is also the preferred modality for screenings, like lung screening for smokers over 50 years of age.

With its unique Siemens SureView™ concept, and a 38-mm detector width, the balance between scan speed and image quality is excellent, Dr. Rothfarb said. SureView’s spiral image reconstruction algorithm facilitates challenging, long scans in clinical routine, for example, in acute care scenarios.

“The Somatom Perspective has a wider gantry than older models which enables patients of larger girth to comfortably be scanned. The shorter depth of the gantry along with the quicker scan speed help reduce any chance of claustrophobia. This also reduces any possible artifact from respiratory motion,” the doctor said.

“The addition of the ultra low dose Somatom CT system compliments and extends the range of quality diagnostic services that CDI offers patients,” said Dr. Rothfarb. “It provides us with vastly improved image quality and speed, enhancing the overall diagnostic confidence.”

Computed tomography (CT) is a medical imaging procedure that uses computer-processed X-rays to produce tomographic images or ‘slices’ of specific areas of the body. These cross-sectional images are used for diagnostic and therapeutic purposes.

Preparing for Your Exam
Be sure to wear comfortable, loose-fitting clothing to your exam. You may be asked not to eat or drink anything four hours before the exam, especially if a contrast material is used. You should inform your physician of any medications you are taking and if you have any allergies. If you have a known allergy to contrast material, or “dye,” your doctor may prescribe medications to reduce the risk of an allergic reaction.

A CT scan may be recommended by a doctor to help:

  • Diagnose muscle and bone disorders, such as bone tumors and fractures
  • Pinpoint the location of a tumor, infection or blood clot
  • Guide procedures such as surgery, biopsy and radiation therapy
  • Detect and monitor diseases such as cancer or heart disease
  • Detect internal injuries and internal bleeding

CT scans can be done even if patients have a pacemaker or an internal cardioverter defibrillator.
