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

Recently, our organization invested in a new computerized axial tomography (CAT) system to better serve our patients. A CAT scan (also called a CT scan) is a non-invasive diagnostic imaging test used to create detailed images of internal organs, bones, soft tissue and blood vessels.

CT is the primary modality used for selecting appropriate treatment in patients with acute stroke symptoms. In these emergency cases, CT team members play an important role by acquiring images in a timely manner for quick treatment that can save lives.

CT is also used for lung cancer screening, using low-dose computed tomography scanning. If lung cancer is found at an earlier stage, when it is small and before it has spread, it is more likely to be treated successfully. This early detection gives lung cancer patients the best chance for remission and recovery.

Our CAT system delivers high definition images by rotating an x-ray source and detector around the patient as they are moved through the device. This provides higher resolution images than previous technologies. Patients get a more diagnostically accurate scan at a lower dose and physicians can quickly obtain the information needed to diagnose and tailor treatments.

Magnetic resonance imaging (MRI) 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.

Our recent $2.7 million renovation and expansion investment accommodates a MRI scanner within the hospital walls (previously, it was located outside, in a mobile unit). 

The 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
• Accommodating heavier patients. 
• Allowing patients choose their favorite nature video, lighting hue, and music during the procedure to create a more soothing environment

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 is the medical specialty that involves the use of radioactive isotopes in the diagnosis of various diseases. MaineHealth Franklin Hospital nuclear medicine services include:

• 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 known as sonography) is used to diagnosis abnormalities as well as guide interventional procedures; such as breast biopsies and needle localizations.

The MaineHealth Franklin Hospital ultrasound department is accredited and provides services within the hospital and at the Martha B. Webber Breast Care Center. Our registered sonographers provide high-quality care with a focus on patient safety and comfort.

Ultrasound services include:

• Abdominal organs
• Ob/Gyn
• Vascular
• Urology
• Infant hips
• Others including: breast, thyroid and scrotal

Our diagnostic imaging department has been accredited by the American College of Radiology (ACR) in:

• CT scan
• Mammography
• MRI
• Nuclear medicine
• 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.
