Medical Imaging

Medical imaging is the specialty that involves the noninvasive production of images of the inside of the human body. These images are used to diagnose and treat diseases. Radiology, which makes up a large part of medical imaging, involves the use of x-rays to obtain visual information. Medical imaging also includes other techniques, such as MRI and Ultrasound, which do not use radiation.


Medical imaging

  • Provide medical imaging services as accurately, safely and promptly as possible.
  • Always be aware of radiation protection and minimization of patient exposure through utilization of appropriate image size, collimation and technical expertise.
  • Maintain open lines of communication between patients, family, physicians, employees and the general public to promote the well-being of the public we serve.
  • Treat all individuals with respect, dignity and kindness at all times.

Imaging Clinical Decision Support

As of January 1, 2020 CMS requires that physicians and advanced practice providers consult a clinical decision support system when ordering advanced imaging procedures in all care settings. This requirement applies to studies performed for Medicare patients at Franklin Community Health Network, Maine Medical Center, Pen Bay Medical Center and Southern Maine Health Care. Critical access hospitals are exempt from this requirement. MaineHealth has implemented the CareSelect imaging clinical decision support tool within Epic, our electronic health record system. Providers who are associated with MaineHealth but do not have access to Epic may access to the CareSelect imaging clinical decision support tool online.

General X-Ray

General w-ray is a simple imaging technique that utilizes x-rays to capture images of internal structures to aid in the diagnosis and treatment of patients' medical conditions. X-rays are most commonly used to look at bones, however, some procedures may include the introduction of a contrast agent to aid in the visualization of the structure and function of different body systems.

CAT Scan

CAT scan (or CT scan) stands for Computerized Axial Tomography. It's a way of using a spinning x-ray and computer to make high-resolution images of the inside of your body. You lie flat on a table that moves through the machine quickly and takes many circular pictures. A computer then puts those pictures together to complete your exam. Any part of your body can be captured and a technologist instructs the CAT scan where to begin and end taking pictures. To enhance difficult to make out areas, some CAT scans are done after injecting you with a special contrast (dye) to clarify indistinct areas. You may also be asked to drink a mixture of contrast, which will highlight your stomach and colon.


MRI021119webMRI, or Magnetic Resonance Imaging, is used to generate images of internal organs and soft tissue inside of the body. This is done by creating a strong magnetic field and then using radio frequency waves to create a detailed picture. Generally, an MRI will be used to see tendons, ligaments, and cysts or other masses. It is the preferred exam for joint and spinal problems because it can provide remarkably clear pictures of soft-tissue structures near and around bones.

A $2.7 million renovation and expansion investment took place in 2018 to accommodate a new Magnetic Resonance Imaging (MRI) scanner within the hospital walls (previously it was located outside in a mobile unit). MRI is a noninvasive medical test that utilizes magnetic fields to produce anatomical images of internal body parts.

The new MRI scanner’s state-of-the-art platform makes it one of the most versatile and powerful systems available with whole body coverage. It features advanced wide-bore technology to improve patients’ experiences by operating with less noise, decreasing feelings of claustrophobia, and accommodating heavier patients. In addition, patients choose their favorite nature video, lighting hue, and music during the procedure to create a more soothing environment.

DEXA (Bone Density)

DEXA, which stands for Dual Energy X-Ray Absorptiometry, is a bone density test that uses a very weak form of x-ray to scan your bones and measure BMD (Bone Mineral Density). Your BMD indicates your bone strength and ability to bear weight. This can be used to diagnose osteoporosis and bone loss. It can also predict your chances of a bone fracture in the future so that you can take steps to increase your bone structure and prevent fractures from happening.

Nuclear Medicine

Nuclear Medicine is the medical specialty that involves the use of radioactive isotopes in the diagnosis of various diseases. Franklin Memorial Hospital Nuclear Medicine offers all the same exams as much larger nuclear medicine facilities, including:

  • Nuclear stress testing of the heart,
  • Bone scanning
  • Kidney scanning
  • Gallbladder scanning
  • Lung scanning
  • Sentinel Node breast exams
  • Thyroid scanning
  • Tumor scanning
  • Infection scanning


Ultrasound, also called sonography, is an imaging technique that uses high frequency sound waves to produce images of the inside of the body. These pictures are a useful way of examining the body’s internal organs, blood vessels, or a developing fetus. Ultrasound is a non-invasive, radiation free diagnostic test. During an ultrasound exam, a clear, jelly-like substance will be applied over the part of the body being examined. A special device called a transducer will then be gently pressed against the body. The transducer records high-frequency sound waves that are sent into the body, and a computer will use this information to produce pictures. These pictures will be evaluated by a Radiologist to help the physician diagnose and treat medical conditions.

Radiation Safety and Quality

The Franklin Memorial Hospital Imaging department has achieved accreditation from the American College of Radiology in the following modalities: CT Scan, mammography, MRI, nuclear medicine, and ultrasound. 


The ACR awards reaccreditation to facilities for the achievement of high practice standards after a peer review evaluation of its practice. Image quality and patient safety. Image quality and procedure evaluations are conducted by board-certified radiologists and medical physicists who are experts in the field. The program also evaluates personnel qualifications, adequacy of facility equipment, quality control procedures, and quality assurance programs. All findings are reported to the American College of Radiology Committee on Accreditation, which subsequently provides the organization with a comprehensive report it can use for continuous practice improvement.
