The use of adjunctive artificial intelligence (AI) reportedly improved lesion level sensitivity by nearly 19 percent and patient level specificity by 14 percent for the diagnosis of clinically significant prostate cancer on multiparametric magnetic resonance imaging (MRI).

An update to Quantib Prostate 2.1, Quantib Prostate 3.0 reportedly facilitates workflow advances and offers a variety of tools, ranging from artificial intelligence (AI)-based segmentation to PI-RADS scoring support, to help improve interpretation of prostate magnetic resonance imaging (MRI).

The FDA granted 510(k) clearance to Unfold AI, which was formerly known as iQuest, in December 2022.

In addition to a previously FDA-cleared brain magnetic resonance imaging (MRI) module, the Advantis Platform features an artificial intelligence-powered prostate MRI module that offers simultaneous viewing of conventional and advanced sequences, and reportedly generates automated PI-RADS assessments.

In a study of over 1,200 men with over 3,200 prostatic lesions, an explainable artificial intelligence (AI) model demonstrated a sensitivity rate of 93 percent for detecting clinically significant prostate cancer.

A new study shows that active surveillance and watchful waiting are being utilized in nearly 60 percent of patients with low-risk prostate cancer in the United States.

In a recent study of a deep learning software in patients with suspected prostate cancer, researchers noted no difference in the detection of clinically significant prostate cancer nor PI-RADS scoring consistency.

The expanded indication could facilitate improved access to imaging for patients with metastatic prostate cancer who are candidates for radioligand treatment.

New research from the American Cancer Society comparing pre-pandemic cancer screening prevalence to the second year of the COVID-19 pandemic in the United States showed a 1.1 million decrease in breast cancer screenings, a 4.4 million decrease in cervical cancer screening and a 600,000 decrease in prostate cancer screenings.

Use of the prostate-specific membrane antigen (PSMA) positron emission tomography (PET) agent piflufolastat F 18 led to treatment plan changes in nearly 40 percent of men with recurrent prostate cancer and low prostate-specific antigen (PSA) levels, according to new research presented recently at the 2023 American Society of Clinical Oncology (ASCO) Genitourinary Cancers (GU) Symposium in San Francisco.

A new study found that approximately one-third of men with prostate cancer were diagnosed with at least one vertebral fracture prior to the initiation of androgen deprivation therapy (ADT).

A new comparative study found the use of prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) led to treatment changes in nearly 20 percent of patients with high-risk prostate cancer.

In a study of nearly 18,000 men who had prostate cancer screening, researchers found the use of pre-biopsy magnetic resonance imaging (MRI) for those with elevated prostate-specific antigen (PSA) levels and reserving MRI-targeted biopsy for those with PI-RADS scores of 3 to 5 reduced the risk of detecting clinically insignificant cancers by half.

The Food and Drug Administration has granted 510(k) clearance to iQuest (Avenda Health), an artificial intelligence (AI) platform that combines findings from magnetic resonance imaging (MRI), pathology reports and biopsy results to facilitate three-dimensional mapping of prostate cancer.

For patients recently diagnosed with prostate cancer, the emerging positron emission tomography (PET) agent 18F-rhPSMA-7.3 reportedly has a 96 percent specificity rate for detecting pelvic lymph node metastases, according to Phase 3 study results recently presented at the 22nd Annual Scientific Meeting of the Society of Urologic Oncology (SUO).

In what may be the first study to assess the effectiveness of biparametric magnetic resonance imaging (MRI) for prostate cancer screening in a large cohort, researchers found that MRI screening had a significantly lower false positive rate and significantly higher positive predictive values (PPVs) than prostate-specific antigen (PSA)-based screening.

New research shows that 18F-NaF PET/CT had higher sensitivity, accuracy, and negative predictive value than 99mTc-MDP SPECT for bone metastases in patients deemed to be at high risk for prostate cancer or breast cancer.

For patients undergoing stereotactic body radiotherapy (SBRT) for prostate cancer, the acute genitourinary (GU) toxicity rate associated with the procedure was 19 percent lower with magnetic resonance imaging (MRI) guidance in comparison to computed tomography (CT) guidance, according to new research presented recently at the American Society for Radiation Oncology (ASTRO) Annual Meeting.

In a recent video interview from the American Society for Radiation Oncology (ASTRO) Annual Meeting, Benjamin Lowentritt, MD discussed the challenges of conventional imaging in diagnosing prostate cancer recurrence and the potential of an emerging high affinity, radiohybrid prostate-specific membrane antigen/positron emission tomography (PSMA/PET) imaging agent.

Five weeks of radiation therapy is just as effective as eight weeks of radiation treatment for men with high-risk prostate cancer, according to new research presented at the American Society for Radiation Oncology (ASTRO) Annual Meeting.
