For HER2-positive breast cancer patients with radiologic complete response on breast MRI after neoadjuvant chemotherapy (NAC), the absence of calcifications was associated with over a 13 percent higher positive predictive value (PPV) for pathologic complete response (pCR).

Researchers also found that low-dose chest CT detection of emphysema was associated with a 29 percent higher risk of all-cause mortality up to 25 years later, according to a study involving over 9,000 individuals with a history of smoking.

Circumferential aneurysm wall enhancement on MRI was associated with a 3.8-fold higher risk of intracranial aneurysm instability within a four-year period, according to a study involving over 1,350 patients.

In a recent interview, Camille Simard, M.D., MSc, discussed findings from a new study assessing elevated risks of spontaneous pregnancy loss and congenital anomalies associated with CT exposure in the month prior to conception.

New research shows that over 94 percent of patients who had a PSA level of < 0.2 ng/mL and low-volume disease assessment six months after initiation of apalutamide and androgen deprivation therapy (ADT) for metastatic hormone-sensitive prostate cancer had radiographic progression-free survival at 24 months.

Encouraging an environment of civility and trust on the social media platforms in radiology may help open more doors for the profession.

In a recent interview, Takeshi Tsuda, M.D., discussed new study findings that show the viability of integrated wall stress as a key diagnostic marker for detecting preclinical cardiomyopathy in patients with Duchenne muscular dystrophy.

For myocardial extracellular volume quantification, single-phase and dual-phase photon-counting CT provided over 20 percent higher correlation with cardiac MRI in contrast to dual-phase energy-integrating detector CT, according to new research findings.

In a recent interview, Zeeshan Shah, M.D., discussed the challenges of addressing rising breast imaging volume amid the radiologist shortage, the potential of emerging AI solutions for bolstering efficient triage and an increasing incidence of breast cancer presentations in younger patients.

Offering the capability to convert a non-contrast chest CT into quantitative ventilation perfusion mapping, use of the CT:VQ software allows for additional Category III CPT reimbursement beyond the chest CT.

While the AI software offered nearly equivalent negative predictive value (NPV) to radiologist interpretation of digital mammograms and digital breast tomosynthesis (DBT) images, researchers noted that AI had significantly higher recall rates and false-positive results in patients with intermediate risk.

In a long-term follow-up analysis of the ELCAP CAC score for predicting cardiovascular mortality, over 30 percent of current or former smokers with high ELCAP CAC scoring on low-dose CT suffered cardiovascular disease death within a 25-year period.

The Revolution Vibe computed tomography system reportedly facilitates quality low-dose imaging for cardiac exams in patients with arrhythmias, heavily calcified coronaries and stents.

In a 10-study meta-analysis examining the use of whole-body MRI for asymptomatic individuals, researchers noted a pooled cancer detection rate of 1.57 percent.
