From routine screening tests to leading edge procedures and imaging modalities, Hoag’s Radiology Department offers the full spectrum of imaging, nuclear medicine and interventional radiology services for cancer patients. Accurate cancer diagnosis and staging are critical in treatment and surgical planning. Hoag’s radiologists are skilled and highly experienced in interpreting oncologic imaging studies and are on the forefront of integrating the newest and most advanced technology for the benefit of patients.

Hoag hospitals and outpatient centers meet the strict requirements set by the DNV National Integrated Accreditation for Healthcare Organizations (NIAHO®) Program, and Hoag Breast Care Center is the only breast center in Orange County, and one of few nationwide, to be designated a Certified Quality Breast Center of Excellence by the National Quality Measures for Breast Centers™.

Radiology and imaging services are available at the ten Hoag locations listed below. (Not all radiology services or imaging modalities are available at every location.)

  • Hoag Hospital Newport Beach
  • Hoag Hospital Irvine
  • Hoag Health Center Aliso Viejo
  • Hoag Health Center Costa Mesa
  • Hoag Health Center Huntington Beach
  • Hoag Health Center Irvine – Sand Canyon
  • Hoag Health Center Irvine – Woodbridge
  • Hoag Health Center Irvine – Woodbury

Hoag’s radiology team is comprised of board certified, fellowship trained, and sub-specialized radiologists, including ten dedicated breast radiologists. The radiologists’ integration with Hoag Family Cancer Institute’s multidisciplinary sitespecific cancer programs and participation in tumor boards enhance coordinated care efforts on behalf of patients.


Imaging Modalities

The complete range of oncologic imaging modalities are available at Hoag, ensuring each patient receives the study or cross-sectional imaging appropriate for their unique case. Advanced technology coupled with the expertise of Hoag’s radiologists means greater ability to detect and diagnose difficult cancers, determine cancer stage and precise location, assess for recurrent disease, and examine treatment response. Hoag’s advanced modalities include:

  • Magnetic Resonance Imaging (MRI) – Four of Hoag’s MRI machines are 3 Tesla (3T). 3T MRI provides enhanced image clarity and greater anatomic detail over 1.5T allowing for improved cancer staging and delineating the extent of disease.
  • Computed Tomography (CT) – The Hoag radiology team optimizes scan parameters that reduce patient dose as much as possible without compromising diagnostic quality.
  • Positron Emission Tomography (PET)
  • PET/CT – PET/CT is applicable to many tumor types and is particularly beneficial in the detection of metastatic disease. Hoag Health Center Irvine – Sand Canyon is home to Orange County’s only FlowMotion™ PET/CT scanning system. With FlowMotion, continuous motion PET/CT scanning produces enhanced image quality while reducing radiation exposure and minimizing the patient’s time on the scanner.
  • PET/MR – Hoag is the first hospital on the West Coast to routinely offer PET/MR to patients. The revolutionary hybrid imaging technology combines the superior soft tissue contrast resolution of MRI with the molecular and functional detail delivered through PET. The modality has been shown to be particularly beneficial in several different tumor types as well as in the detection of metastatic disease.
  • Ultrasound – Hoag offers Ultrasound Elastography to assess for liver fibrosis, which can be a precursor for liver cancer. Hoag also offers the latest ultrasound systems for various cancer screenings.
  • Specialized breast imaging including 3D Mammography, Breast MRI, and Breast Ultrasound, provide the full complement of diagnostic services. Hoag is among the highest volume providers of 3D mammography in the United States. Nuclear Medicine In some cases, nuclear medicine imaging can provide unique functional information that is not accessible on other imaging scans. Hoag offers comprehensive nuclear medicine services for the diagnosis and treatment of cancers. In the last year, several new advances and protocols have been added including:
  • Gallium-68 Dotatate with PET/CT or PET/MR Scanning provide enhanced images for the detection and staging of neuroendocrine tumors over octreotide scans. Hoag implemented Gallium-68 Dotatate scanning shortly after it was approved by the FDA in 2016.
  • New Radioiodine imaging with single photon emission computed tomography (SPECT/CT) improves diagnostic imaging of thyroid cancers.
  • The radiotracer,Fluciclovine F18 (Auxmin®) was recently approved for prostate cancer imaging. Hoag utilizes the radiotracer with PET/CT and PET/MR to detect early prostate cancer recurrence on a molecular level in patients after surgery. It can even detect recurrence in patients with PSA levels less than one.
PET/MR images using Gallium-68 Dotatate in patient with metastatic carcinoid cancer including a right scapular metastasis and multiple liver mets.

Interventional Radiology

Interventional radiology procedures can provide cancer patients an effective, minimally invasive treatment option in appropriate circumstances. Hoag’s fellowship-trained interventional radiologists maintain a high volume of oncologic interventional radiology procedures including cryoablation, microwave ablation, radioembolization (Y90) utilizing resin and glass microspheres, chemoembolization, and image-guided biopsies.

Hoag is among the first to use PET/MR scanning post Y90 treatment to evaluate the accuracy of the distribution of the Y90. PET/MR immediately provides the clearest picture possible to determine if the dose was distributed accurately or if additional treatment is needed, a significant advance over Bremsstrahlung scanning.
