About Us

The Department of Radiology is comprised of physicians, radiologic health professionals, nurses, administrative coordinators, schedule coordinators and secretaries who work together to provide a comprehensive array of diagnostic and therapeutic imaging services. 

HUMC: A Diagnostic Imaging Center of Excellence

The American College of Radiology (ACR) has recognized Hackensack University Medical Center as the first-ever Diagnostic Imaging Centers of Excellence Award recipient. This elite distinction recognizes HUMC’s excellence in diagnostic imaging. The award was presented to Harry Agress Jr., M.D., FACR, Chairman Emeritus, Department of Radiology and director of the PET/CT Center and Division of Nuclear Medicine, during ACR’s annual meeting in Washington, D.C., on Tuesday, May 7, 2013. As one of only two centers nationwide to receive this designation, Hackensack UMC stands as one of the best radiology hospitals in New Jersey and the greater northeastern region.

The radiologic technologists of the Department of Radiology are dedicated to obtaining the most accurate diagnostic information possible. The team is comprised of highly skilled men and women who are certified by The American Registry of Radiologic Technologists and the New Jersey State Department of Health. Ultrasound professionals are certified by the Registry of Diagnostic Medical Sonographers.

Technologists work closely with patients to obtain optimal images. They operate radiographic equipment to produce the images, which are then presented to the radiologists for diagnostic interpretation. Technologists can specialize within the field of radiology and work exclusively with select procedures. Other imaging professionals can specialize in certain procedures as well. Some of the more common technologists include:

  • Computerized Tomography (CT) Technologist

  • Magnetic Resonance Imaging (MRI) Technologist

  • Nuclear Medicine Technologist

  • Special Procedures Technologist

  • Ultrasound Technologist

  • Radiologic Technologist

  • Bone Density Technologist


Computerized Tomography (CT) Technologist - CT technologists have specialized CT skills and perform examinations that produce cross-sectional images of the anatomy. Many different exams are performed by CT technologists, ranging from a simple CT scan of the head to assisting an interventional radiologist in complex procedures like biopsies and abscess drainages. A CT technologist is also skilled in three-dimensional image processing, which results in greater diagnostic accuracy.

Magnetic Resonance Imaging (MRI) Technologist - MRI technologists have extensive training in physics and cross-sectional anatomy. MRI is a powerful diagnostic tool that has undergone unprecedented growth. MRI technologists need to remain current with the technological advances in the field and the new applications that are developed for this modality.

Nuclear Medicine Technologist - Nuclear medicine technologists are highly specialized healthcare professionals who work closely with physicians in this field. Some of the primary responsibilities of nuclear medicine technologists include:

  • preparing and administering radioactive chemical compounds, known as radiopharmaceuticals.
  • performing imaging procedures using sophisticated instrumentation and nuclear equipment.
  • processing and enhancing computer images.
  • providing images, data analysis and patient information to the nuclear medicine radiologist for diagnostic interpretation.

Special Procedures Technologist - Special procedures technologists are skilled in assisting interventional radiologists, who diagnose and treat patients with the use of imaging techniques that guide them as narrow tubes (catheters) are threaded through blood vessels to the site of a problem.

Ultrasound Technologist - Ultrasound technologists, also called medical sonographers, perform ultrasound examinations to obtain and produce images of internal organs. This modality is also used to monitor the health of an unborn baby. These specialists analyze ultrasound images to be certain that the radiologist has optimal images for diagnostic interpretation.

Radiologic Technologist - Radiologic technologists, also called radiographers, use X-rays to obtain images of various body parts and the function of certain organs. The images they produce are presented to a radiologist to screen and diagnose diseases and conditions.

Bone Density Technologist - Certified Bone Densitometry Technologist (CBDT™) is a professional certification in the field of bone densitometry for technologists who perform densitometry scans.



Patients undergoing certain imaging tests and procedures at the medical center are tended to by a nurse who monitors vital signs, assists radiologists during examinations or therapeutic procedures, provides instructions for recovery and teaches preventive health measures. These nursing specialists also provide for the physical, mental and emotional needs of patients and their families.
