Article Synopsis
- This study assesses the effectiveness of three AI algorithms for segmenting prostate regions in MRI scans of patients with complex medical backgrounds and varied anatomical features.
- The researchers analyzed data from 683 MRI scans, ensuring that they included criteria such as previous treatments and different scanner qualities, and compared the AI’s segmentation against expert radiologist assessments.
- Results showed that deep learning models significantly outperformed other methods, especially in cases with smaller prostate volumes and better image quality, highlighting the challenges presented by variances in anatomy and scan conditions.
Accurate determination of the local stage of prostate cancer is crucial for treatment planning and prognosis. The primary objective of local staging is to distinguish between organ-confined and locally advanced disease, with the latter carrying a worse clinical prognosis. The presence of locally advanced disease features of prostate cancer, such as extra-prostatic extension, seminal vesicle invasion, and positive surgical margin, can impact the choice of treatment.

Quality degradation sources exert varying impacts based on the sequence under consideration, such as T2W versus DWI.

- MRI/ultrasound fusion-guided targeted biopsy (TBx) is essential for effective management of prostate cancer by helping with precise risk stratification.
- This study compared the performance of two versions of the PI-RADS scoring system (v2.0 and v2.1) in predicting changes in cancer severity after TBx and subsequent radical prostatectomy (RP).
- Results showed no significant differences in upgrade or downgrade rates between the two versions, indicating that both versions are equivalent in assessing clinically significant prostate cancer.
Background: Public health programs are tasked with educating the community on health topics, but it is unclear whether these programs are acceptable to learners. Currently, these programs are delivered via a variety of platforms including in-person, virtually, and over the telephone. Sickle cell trait (SCT) education for parents of children with this trait is one of many education programs provided by the Ohio Department of Health.

Pre-pandemic, Ohio offered in-person SCT education for parents of SCT-affected children but many did not attend. Those with limited health literacy (HL) were less likely to achieve high knowledge.
