Oncology Imaging

Medical imaging has become integral to cancer care, assessing the stage and location of cancerous tumors. By utilizing powerful imaging modalities including CT, MRI, MRA and PET/CT, oncology imaging radiologists are able to assist referring physicians in the detection and diagnosis of cancer.

Implementing an EHR cancer tracking system to review radiology reports for abnormal findings resulted in patients at one Veterans Affairs Hospital receiving their cancer diagnosis and treatment months earlier than those who were imaged before the system was put into place.

The authors stated that their results should not deter providers from offering their patients radiotherapy treatment but rather encourage in-depth discussions and shared decisions pertaining to the best options.

Prostate Cancer

Using hybrid multidimensional MRI exams in lieu of multiparametric MRI for the assessment of prostate cancer could reduce interpretation times while increasing interobserver agreement. 

Individuals at high risk of pancreatic cancer benefit from annual imaging and have decreased mortality rates compared to those who forgo preventive screening.  

Lung

Experts observed significantly reduced pneumothorax and pulmonary hemorrhage rates of 8% and 6% when utilizing the method.

PET/CT imaging in these patients increases overall survival depending on the cancer’s stage, with those diagnosed with stage 3A and 3B NSCLC appearing to benefit the most from the exam.

The model performed well in assessing treatment responses, but experts explained that one of the most beneficial aspects of their model was that its results are interpretable in a “clinician-friendly way.” 

An international panel of experts recently developed and validated a reporting assessment scoring system that analyzes the location and extent of prostate cancer recurrence. 

Preoperative MRI use increased substantially from 2003 to 2016—from 2.9% to 28.2% to be exact—but the modality remained underutilized in certain regions and among specific populations in the United States.

For the research, special attention was paid to women with dense breasts and other factors that raise their risk of a breast cancer diagnosis.

The study touts the benefits of targeted radionuclide alpha therapy for patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) who have not had success with other treatments.

Men with prostate cancer can avoid many of the unpleasant side effects of chemo, surgery and radiation therapy when they are treated with high-intensity focused ultrasound instead.

Salvage radiation therapy guidelines for patients with prostate cancer recurrence need to be updated to include findings identified on PSMA PET, according to new research shared at SNMMI’s annual conference this week. 

Around the web

There is not agreement among the top structural heart experts if CT is required for left atrial appendage occlusion (LAAO), but a Henry Ford Hospital study shows it can improve outcomes.

Ron Blankstein, MD, Brigham and Women's Hospital, explains recent advances in coronary computed tomography angiography (CCTA) technology. 

With the elevation of cardiac CT to a 1A indication in the 2021 Chest Pain Guidelines, there has been a large amount of interest in starting coronary artery CT angiography (CCTA) programs.
