ECHN’s imaging and testing services utilize the latest techniques and technology to give you and your physician rapid and reliable results. There are a number of conveniently located imaging and testing centers throughout ECHN.

Bone Density Scan

Bone Density testing is a non-invasive scan that uses X-rays to measure the amount of calcium and minerals in the bones to determine the risk level for bone fractures or osteoporosis.

Cardiac Nuclear Medicine

Cardiac Nuclear Medicine is a non-invasive diagnostic imaging test that evaluates the heart. It detects coronary artery disease, cardiomyopathy and heart damage from chemotherapy or radiation. After administration of a radioisotope or radioactive medication, a camera captures images of the heart and the surrounding arteries.

CT Scan

A CT or CAT Scan (computed tomography/computerized axial tomography) is a non-invasive diagnostic test that generates multiple cross-sectional images of internal organs, bones, soft tissue and blood vessels using X-rays and a computer. Sometimes CT Scans require the use of contrast medication to highlight organs and blood vessels in greater detail.

Interventional Radiology

Interventional Radiology, also known as vascular interventional radiology, is a minimally invasive image-guided procedure to help diagnose and treat disease. These procedures have less risk, pain and recovery time as compared to open surgery.



Mammography, more commonly referred to as a mammogram, is a type of non-invasive imaging that uses low-dose X-ray radiation to examine breast tissue. It is recommended that women over the age of 40 have a screening mammogram every year. In the event that a screening mammogram results in finding an abnormality, a diagnostic mammogram may be recommended to further examine the area of concern.

MRI (Magnetic Resonance Imaging) is a diagnostic exam that uses a powerful magnetic field and radio waves to produce images of the body’s internal structures. It results in a more clear and detailed image than an X-ray or ultrasound. MRI’s sometimes require the use of a contrast dye injection to highlight organs and blood vessels in greater detail.

MRI Biopsy

MRI-guided biopsy is used when a traditional ultrasound-guided biopsy is not appropriate because the area of concern cannot be seen well by an ultrasound.

Nuclear Medicine

Nuclear Medicine is a diagnostic imaging test that takes a detailed picture of the body at the cellular and molecular level in order to visualize the structure and function of an organ, tissue, bone or system within the body. After administration of a radioactive medication, a rotating camera captures a series of images.


A PET Scan (positron emission tomography) is a diagnostic imaging test that examines the chemical activity and function of tissues and organs. This test requires administration of a radioactive tracer to collect in areas of the body that have higher levels of chemical activity or disease. A PET Scan can provide information that is not detected by a CT Scan or MRI.

Stereotactic Breast Biopsy

A Stereotactic Breast Biopsy uses mammography to precisely identify and biopsy an abnormality. This procedure is usually performed when a radiologist discovers an abnormality on a mammogram that cannot be felt through a physical exam.

An ultrasound, also known as sonography, is an external diagnostic exam that uses sound waves in order to create images of organs, soft tissues, blood vessels and other structures inside the body. Ultrasounds are often used to help diagnose unexplained pain, swelling and infection, and are the preferred imaging method for monitoring pregnancies.

Ultrasound-Guided Biopsy

Ultrasounds are used to provide imaging guidance for a needle biopsy in order to take a small tissue sample of a lump or abnormality within the body. Ultrasound-guided biopsies are less invasive than surgical biopsies, and they leave little to no scarring.


X-rays are imaging tests that produce pictures of soft tissue, bones or organs. The area of the body that is receiving the X-ray is exposed to a very small dose of radiation in order to generate images of the body part at multiple angles. X-rays are non-invasive and are usually used to examine the chest, abdomen, upper and lower extremities.
