CARTI offers the most technologically advanced, comprehensive diagnostic radiology available and is accredited by the American College of Radiology.

Our diagnostic radiology services are now available for outside referrals for non-malignant diagnostic exams. If you or a family member would like to have your diagnostic radiology services done at CARTI, simply talk to your doctor when the referral is made.

CARTI’s team of diagnostic radiologist is led by David Hays, M.D., and includes  additional board-certified physicians Donald Norwood, M.D., Peter Lindley M.D. and Theodore Hronas, M.D. You can rely on CARTI for state-of-the-art services in all areas of diagnostic radiology, including lung screenings, diagnostic CT, nuclear medicine, PET-CT scans, ultrasound and interventional radiology. Working with CARTI allows you to expand the quality of patient services by teaming with a leader in the diagnostic radiology field.

Our Services


FDG PET CT (Positron Emission Tomography)

The most common type of PET procedure uses the imaging agent FDG, a radioactive form of the sugar glucose. It measures the metabolic activity of tissues. Because cancerous tumors are usually more metabolically active than normal tissues, they appear different from other tissues. A PET CT combines CT’s fine anatomical detail with PET’s ability to detect biochemical abnormalities in the cell allowing for earlier and more accurate detection of disease than either CT or PET alone. Combining PET/CT may improve the ability to diagnose cancer, determine how far a tumor has spread, plan treatment and monitor response.

Sodium Fluoride (18F NaF) Bone Scan

Bone scans are essential tools in the diagnosis of bone metastases in cancer patients, especially those with cancers (such as breast and prostate) that tend to metastasize to bone. The Sodium Fluoride (F18) Bone Scan has the ability to detect disease earlier with greater sensitivity than traditional SPECT or planar bone imaging. It also has increased sensitivity and detection of occult bone fractures or infections.

Instructions for your PET Scan


An MRI or Magnetic Resonance Imaging is a safe and painless scan that uses a magnetic field and radio waves to produce detailed pictures of the body’s organs and structures. The MRI machine CARTI has is the Philips Ingenia 3.OT,  one of only two currently being used in the United States. This MRI produces incredibly detailed images of body structures in about 30 minutes and also has a light and video system to ease patients’ claustrophobia.

Nuclear Medicine

CARTI is equipped to conduct a full range of nuclear medicine diagnostics, including whole body bone scans, myocardial perfusion scans, hepatobiliary scans and gastric emptying scans, parathyroid scan, liver/spleen scan, and liver/spleen SPECT imaging.

Nuclear Medicine Whole Body Bone Scan

The nuclear medicine whole body bone scan is generally used in evaluations of various bone-related pathology, such as bone pain, stress fracture, nonmalignant bone lesions, bone infections, or the spread of cancer to the bone.

Hepatobiliary Scan

Hepatobiliary imaging evaluates a patient’s liver, gallbladder and the ducts of the biliary system to diagnose gallbladder disease, acute biliary obstructions.

Gastric Emptying Scan

Patients with gastric motility disorders, or who are experiencing nausea, vomiting, abdominal pain, or GERD may need a gastric emptying study to determine how fast food is leaving the stomach.

Liver/Spleen Scan

A scan to evaluate the function of the liver and surrounding organs. Liver scans can detect abdominal masses, abnormal liver function and evaluate the spleen.


Ultrasound imaging allows an inside view of soft tissues and body cavities without the use of invasive techniques. CARTI offers abdominal ultrasounds (including pancreas, aorta, IVC, kidneys, gallbladder, spleen, liver, and renal), carotids, scrotal ultrasounds and upper and lower extremity venous Doppler.

DEXA Bone Densitometry

Dual Energy X-Ray Absorptiometry (DEXA) measures bone mineral density. DEXA scans are the best method of diagnosing and monitoring osteopenia and osteoporosis.

Interventional Radiology

CARTI’s radiology staff can perform paracentesis, thoracentesis and miscellaneous CT and ultrasound-guided biopsies, and placement of central venous lines, peripheral intravenous lines, and Kopans needle localizations.

Low Dose CT Scans for Lung Screenings

Computed tomography (CT) is a non-invasive imaging procedure that can be performed on every region of the body for screening, diagnostic evaluations, treatment planning, and interventional purposes. In addition to detecting abnormal growths, diagnosing tumors and providing information on the stage of cancer and/or whether it is responding to treatment, CT scans help diagnose circulatory system diseases, inflammatory diseases and injuries to the head, skeletal system and internal organs.

Low-Dose Healthy Lung Screening

The National Lung Screening Trial (NLST), sponsored by the National Cancer Institute, showed that people aged 55 to 74 with a history of heavy smoking and a high risk for developing the disease are 20 percent less likely to die from lung cancer if they are screened with low-dose helical CT. CARTI’s low-dose screening program allows screening for early stage lung cancer for those who are highest risk, while limiting the patients’ exposure to radiation.

Qualifying patients must be:

  • Current or former smokers (aged 55 to 74 years old)
  • Smoking history of at least 30 pack years (pack years is number of packs per day times number of years, i.e., 2 packs per day x 15 years = 30 pack years)
  • No history of lung cancer

Diagnostic Imaging

CARTI offers x-rays for diagnostic radiography for all of a patients’ needs.



CARTI’s Imaging Department offers some of the highest quality technology in the state, and access to some of the well-respected diagnostic radiologists in the country. When you have your diagnostic radiology procedures done at CARTI, you can be assured you will receive state-of-the-art evaluations. Results will be timely and imaging will be available for the patient and their physician’s review on the day of the exam. The written report will be available within 24 hours or the next business day. Our patients are greeted by a friendly staff and their exam will be performed with minimal wait times.

How To Refer

Tell your physician you would like to have your procedure done at CARTI. For a referral, have your doctor call 906-4429 or 844.552.2784 and ask for CARTI’s Imaging Division.
