Prostate biopsy is essential in diagnosing prostate cancer. The Prostate Imaging-Reporting and Data System (PI-RADS) and magnetic resonance imaging (MRI)-transrectal ultrasound fusion-guided biopsy are also useful for diagnosis. However, the burden of implementing and maintaining these techniques should be considered. Therefore, we investigated the significance of non-standardized pre-biopsy MRI abnormalities (conditions not in accordance with PI-RADS) and subsequent targeted biopsy. We collected clinicopathological data, including the presence or absence of MRI abnormalities, through biopsies from January 2017 to February 2022 at the Kanagawa Cancer Center and performed statistical analyses. We enrolled in 1086 cases: MRI abnormalities were observed in 861 cases (79.3%). In these 861 cases, the adenocarcinoma detection rate, number of positive cores, and length of the highest Grade Group (GG) lesions were significantly higher. In the multivariate analysis, MRI abnormalities were the most significant factor for detecting adenocarcinoma of ≥GG 2 (odds ratio: 4.52, 95% confidence interval: 3.08-6.63). Targeted biopsy showed a higher percentage of positive cores with ≥GG2 and longer highest GG lesion lengths than systematic biopsy. Furthermore, the highest GG was upgraded in 109 of 788 cases by targeted biopsy. However, several adenocarcinomas (125/788; 15.9%) could not be detected using only targeted biopsy. Non-standardized MRI abnormalities are powerful predictors of cancer and grading. Targeted biopsies based on MRI abnormalities provide several benefits. Owing to the relatively low implementation hurdle, these biopsies may serve as a bridge until the ideal approaches are popularized if the limitations are well understood.

Objective: Epilepsy is a common neurological disease affecting nearly 1% of the global population, and temporal lobe epilepsy (TLE) is the most common type. Patients experience recurrent seizures and chronic cognitive deficits that can impact their quality of life, ability to work, and independence. These cognitive deficits often extend beyond the temporal lobe and are not well understood.

Neoplastic meningitis, also known as leptomeningeal metastases, is a rare clinical entity seen in less than 1%-2% of primary nervous system tumors. Diagnosis of leptomeningeal metastases is difficult and is achieved by cytologic evidence of malignant cells in cerebrospinal fluid, or demonstration of radiologic abnormality. 18F-FDG PET/CT can detect leptomeningeal metastases before anatomical changes.

Case: A 16-year-old woman presented with acute on chronic knee pain and instability following a twisting injury. The tibial insertion of the anterior cruciate ligament (ACL) was nonvisualized on magnetic resonance imaging. A cord-like ACL, originating from the lateral intercondylar notch and inserting smoothly into the anterior horn of the intact lateral meniscus, was found on arthroscopy.

Optimal management of adult congenital heart disease (ACHD) requires a multidisciplinary team (MDT) approach, fostering a collaborative culture over an individualistic approach. Within this framework, subspecialty-trained radiologists provide crucial imaging expertise, supporting cardiologists, surgeons, and interventional cardiologists in diagnoses, treatment planning, and follow-up evaluations. Advanced imaging tools and a nuanced understanding of surgical and interventional procedures enable radiologists to provide valuable insights to clinicians.

Importance: Neonatal protein intake following very preterm birth has long lasting effects on brain development. However, it is uncertain whether these effects are associated with improved or impaired brain maturation.
Objective: To assess the association of neonatal protein intake following very preterm birth with brain structure at 7 years of age.
