Nashoba Valley Medical Center's (NVMC) diagnostic imaging department includes a sophisticated and comprehensive facility with state-of-the-art imaging technology, including digital radiography, nuclear medicine, CT scanning, digital fluoroscopy, MRI, general ultrasound, vascular ultrasound, digital mammography and bone densitometry.
CT (computed tomography) or commonly known as "CAT scans," is a diagnostic imaging test that uses a combination of X-rays and computer technology to create images. A series of X-ray beams from many different angles are used to create a cross sectional image of the body part being scanned. Spiral scanning is a constant X-ray beam obtained while the table is moving and is used to acquire a larger area of data with no interruptions. This is extremely useful to view blood vessels with the use of intra-venous X-ray contrast.
New, 64-slice CT scanner with specialized software called iDose that reduces overall radiation exposure to the patient while providing optimal imaging for accurate diagnosis. This new technology allows the Diagnostic Imaging Department at Nashoba Valley Medical Center to offer state-of-the-art care to our patients close to home. NVMC's CT Scan department is fully accredited by the American College of Radiology
Unlike conventional X-ray examinations, nuclear medicine uses a radioactive material that is usually injected into the patient's body and is the detected by a "gamma camera". Most radioactive materials are eliminated from your body rapidly. Nuclear scans in general look more at organ function than anatomy and therefore compliment other areas of diagnostic imaging.
Ultrasound is a diagnostic procedure that uses very high-frequency sound waves to produce an image of the internal structures of the body. NVMC's ultrasound department is fully accredited by the American College of Radiology.
Vascular Ultrasound is an exam that looks at the blood vessels to see whether there are any areas of dilation, narrowing or blockage. The vessels most frequently looked at are in the neck, arms and legs, including arteries and/or veins as well as assessment of bypass grafts.
Magnetic resonance imaging (MRI) is a diagnostic procedure that produces images of the body without the use of X-rays. The images are created using a magnet, radio waves and a computer system. Our equipment is a start-of-the-art Philips 1.5 tesla, short bore magnet that creates sharp, precise images that is used as a diagnostic tool for the physicians planning the medical treatment for their patients. The MRI scanner recently went through a major upgrade that replaced components and software to provide the latest platform to enhanced MRI functionally including new acquisitions techniques to better serve our patients. NVMC's MRI department is fully accredited by the American College of Radiology.
MRI appointments are available six days per week, Monday through Saturday with early and late appointment options. Scheduling can be done Monday through Friday, 8:30 a.m. to 4 p.m. by calling 978-784-9400.
If you require images on film or CD this will require a 24 hour notice. Please call 978-784-9000, ext. 4286 to verbally request your images. Fax your request to 978-784-9550 and include a signed notice with the name, date of birth, phone number and the address of the facility to which you would like the images sent.
