Radiolabeled prostate-specific membrane antigen PET (PSMA PET) is emerging as an important modality for imaging prostate cancer (PCa). Promising clinical experience has led to increasing number of studies exploring the role of PSMA PET in different aspects of PCa including primary detection, risk stratification, targeted biopsy, initial staging, restaging at biochemical recurrence, biologic characterization, treatment response assessment and prognostication. PSMA PET may prove an important disease biomarker, expand our understanding of the pathogenesis and pave the way for personalized management of PCa...

REVIEW

Prostate cancer is the most common cancer and the second leading cause of cancer death in men in the United States. Despite high prevalence, diagnosis and surveillance is limited due to indolent biology. Functional imaging techniques improved the ability to detect disease. Amino acids are building blocks of proteins and intracellular transport is upregulated in prostate cancer. Normal biodistribution patterns of fluciclovine include uptake in the liver and pancreas with minimal to no urine excretion, a distinct advantage for prostate cancer imaging...

REVIEW
Paolo Castellucci, Francesco Ceci, Stefano Fanti
This article reviews the role of 11 C-choline-PET/computed tomography (CT) in patients with prostate cancer for diagnosis, staging, and restaging the disease in case of biochemical recurrence after primary treatment. The main application of this imaging procedure is restaging of the disease in case of biochemical recurrence. 11 C-Choline-PET/CT proved its value for metastases-directed salvage therapies and for monitoring therapy response in castration-resistant patients. Prostate-specific antigen and prostate-specific antigen kinetics values confirmed their correlation with 11 C-choline PET/CT sensitivity...

REVIEW

Prostate multiparametric MR imaging (mpMRI) plays an important role in local evaluation after treatment of prostate cancer. After radical prostatectomy, radiation therapy, and focal therapy, mpMRI can be used to visualize normal post-treatment changes and to diagnose locally recurrent disease. An understanding of the various treatments and expected changes is essential for complete and accurate post-treatment mpMRI interpretation.

Meaningful changes to the approach of prostate cancer staging and management have been made over the past decade with increasing demand for high-quality multiparametric MR imaging (mpMRI) of the prostate. This article focuses on the evolving paradigm of prostate cancer staging, with emphasis on the role of mpMRI on staging and its integration into clinical decision making. Current prostate cancer staging systems are defined and mpMRI's role in the detection of non-organ-confined disease and how it has an impact on the selection of appropriate next steps are discussed...

mp-MRI of the prostate is a complex study that combines anatomic and functional imaging. The complexity of this technique, along with an increasing demand, has brought new challenges to imaging interpretation. The Prostate Imaging Reporting and Data System provides radiologists with guidelines to standardize interpretation. This article discusses the interpretation of the pulse sequences recommended in the Prostate Imaging Reporting and Data System version 2 guidelines, reviews advanced quantitative imaging tools, and discusses future directions...

Multiparametric MR imaging provides detailed anatomic assessment of the prostate as well as information that allows the detection and characterization of prostate cancer. To obtain high-quality MR imaging of the prostate, radiologists must understand sequence optimization to overcome commonly encountered technical challenges. This review discusses the techniques that are used in state-of-the-art MR imaging of the prostate, including imaging protocols, hardware considerations, and important aspects of patient preparation, with an emphasis on the recommendations provided in the prostate imaging-reporting and data system version 2 guidelines...

This review article aims to provide an overview on of diffusion-weighted MR imaging (DW-MR imaging) in the urogenital tract. Compared with conventional cross-sectional imaging methods, the additional value of DW-MR imaging in the detection and further characterization of benign and malignant lesions of the kidneys, bladder, prostate, and pelvic lymph nodes is discussed as well as the role of DW-MR imaging in the evaluation of treatment response.

REVIEW
Siva P Raman, Elliot K Fishman
Computed tomography (CT) urography is the best noninvasive method of evaluating the upper urinary tract for urothelial malignancies. However, the utility of CT urography is heavily contingent on the use of proper image acquisition protocols. This article focuses on the appropriate protocols for optimizing CT urography acquisitions, including contrast administration and the timing of imaging acquisitions, as well as the use of ancillary techniques to increase collecting system distention. In addition, imaging findings are discussed that should raise concern for urothelial carcinoma at each of the 3 segments of the urinary tract: the intrarenal collecting systems, ureters, and bladder...

Various pathologies can affect the adrenal gland. Noninvasive cross-sectional imaging is used for evaluating adrenal masses. Accurate diagnosis of adrenal lesions is critical, especially in cancer patients; the presence of adrenal metastasis changes prognosis and treatment. Characterization of adrenal lesions predominantly relies on morphologic and physiologic features to enable correct diagnosis and management. Key diagnostic features to differentiate benign and malignant adrenal lesions include presence/absence of intracytoplasmic lipid, fat cells, hemorrhage, calcification, or necrosis and locoregional and distant disease; enhancement pattern and washout values; and lesion size and stability...

REVIEW
Fernando U Kay, Ivan Pedrosa
The increase in serendipitous detection of solid renal masses on imaging has not resulted in a reduction in mortality from renal cell carcinoma. Consequently, efforts for improved lesion characterization have been pursued and incorporated into management algorithms for distinguishing clinically significant tumors from those with favorable histology or benign conditions. Although diagnostic imaging strategies have evolved for optimized lesion detection, distinction between benign tumors and both indolent and aggressive malignant neoplasms remain an important diagnostic challenge...

Since its clinical inception a decade ago, dual-energy computed tomography has expanded the array of computed tomography imaging tools available to the practicing abdominal radiologist. Of note, diagnostic solutions for imaging-based evaluation of genitourinary diseases, foremost kidney calculi and renal tumors characterization, represent the apogee applications of dual-energy computed tomography in abdominal imaging. This article reviews clinical applications of dual-energy computed tomography for the assessment of genitourinary diseases...

Neoadjuvant chemotherapy improves survival in patients with muscle-invasive bladder cancer. However, a significant proportion of patients are ineligible for cisplatin owing to renal impairment or other medical comorbidities. The introduction of anti-programmed cell death protein 1/programmed death-ligand 1(PD1/PD-L1) checkpoint inhibitors has redefined the therapeutic landscape for platinum-resistant urothelial cancers; their clinical efficacy and favorable toxicity render these agents attractive therapeutic options either as monotherapy or in combination with other agents in earlier disease states, including muscle-invasive disease...

A select group of patients with upper tract urothelial carcinoma (UTUC) may meet indications for endoscopic management. Strategies for disease management are provided, based on a comprehensive review of the data using PubMed and Medline databases and marrying this with our experience with endoscopic management of UTUC. Endoscopic management of UTUC via retrograde or antegrade approaches is a viable treatment option for appropriately selected patients with low-risk UTUC, including those with low-grade, low-volume, and solitary tumors...
