Cervical disc arthroplasty: Review and update for radiologists
An increasing number of cervical artificial discs are being implanted in the United States. Successful imaging evaluation of preoperative cervical disc arthroplasty candidates and postoperative patients requires an understanding of patient selection criteria, hardware design, and imaging appearances of normal hardware and the spectrum of postoperative complications.

Multiparametric MRI: An opportunity for focal therapy of prostate cancer
Focal therapy of prostate cancer aims to target cancer containing areas of prostate while leaving surrounding native tissue preserved, thus decreasing the risk of complications seen in whole gland treatments like radical prostatectomy and external beam radiation therapy. However, an intrinsic obstacle to the widespread implementation of the focal therapy is the tendency of prostate cancer to exhibit multifocality. For this reason, it is of paramount importance to ensure accurate disease localization prior to recommending this treatment option to patients, in order to avoid missing potentially aggressive cancers.

Imaging Prostate Cancer Using Multiparametric Magnetic Resonance Imaging: Past, Present, and Future
Medical imaging is ubiquitous in modern patient care. Its history, however, can be traced back as far as the 19th century. Wilhelm R öntgen first described the ability to identify the bony structures of the hand at the University of Würzberg in 1894, with his subsequent work earning him the Nobel Prize in Physics in 1901 and spurring a new era in medical technology.1 Though the magnetic properties of protons had been known sinc e the 1940s, it would be decades until such technology could be harnessed for the benefit of patients.

Imaging Prostate Cancer Using Multiparametric Magnetic Resonance Imaging: Past, Present and Future
Magnetic resonance imaging of prostate is currently widely used for diagnosis and staging of prostate cancer. First utilized in the early 1980s, MRI technology was rapidly recognized as a promising technique for characterizing pelvic and specifically prostatic anatomy. Further advancements, including the addition of diffusion weighted imaging and dynamic contrast enhanced imaging have continued to propel MRI into the forefront of prostate cancer care, notably with the development of the multiparametric MRI.

A Review of Prostate Biopsy Techniques
Imaging of the prostate has improved dramatically over the last few decades and has led to the improved detection, staging, and treatment of prostate cancer. Technologies such as multiparametric magnetic resonance imaging (mpMRI) identify three-dimensional regions of interest (ROI) suspicious for prostate cancer, which can then be targeted for biopsy. This is moving us away from the systematic non-targeted biopsies of the past where the entire prostate is sampled. The implementation of this technology has the potential to more accurately stage prostate cancer at the initial diagnosis, therefore pushing men with clinically ...

Septic Arthritis and Joint Aspiration: The Radiologist ’s Role in Image-Guided Aspiration for Suspected Septic Arthritis
Septic arthritis must be considered in the setting of an acute hot and swollen joint. This disease entity is disabling and potentially life-threatening, destroying cartilage within days of onset, and with a reported mortality rate of 5%-50%.1-8 A delay in diagnosis has been described as a major contributor to poor outcome.2,4,7-9 (Source: Seminars in Roentgenology)

Magnetic Resonance Imaging-Transrectal Ultrasound Fusion Biopsy of the Prostate —An Update
Prostate cancer (PCa) is amongst the most common malignancies in males. Based on the recent Surveillance, Epidemiology, and End Results Programme (SEER) data for 2017, PCa accounts for 9.6% of all the newly diagnosed cancers and 4.4% of all the cancer-related deaths.1 A large majority of the biopsy-proven PCa are indolent and do not result in increased mortality, as indicated by the high 5-year survival rate of 98.6%.1 This translates into the need for vigorous follow-up care and active surveillance, which potentially adds to the expense and emotional burden on the patient.

Multiparametric Magnetic Resonance Imaging in the Evaluation of Prostate Cancer Recurrence
Prostate cancer (PCa) remains a major cause of morbidity and mortality in men, with 164,690 new cases and 29,430 deaths expected in 2018.1 Multiple treatment options for PCa exist. The choice of therapy usually depends on clinical parameters such as life expectancy and tumor grade and stage, as well as the treating physician ′s experience and the patient′s preference (Table 1).

MRI- TRUS Fusion Biopsy of the Prostate- An Update ☆☆☆☆
Prostate cancer (PCa) is one of the most common malignancies in males. The current standard of care for the diagnosis of PCa is Transrectal ultrasound (TRUS) guided systematic biopsy of prostate. Patients with clinical suspicion of PCa undergo systematic TRUS-guided biopsy for diagnosis, localization and grading of the tumor. Systematic biopsies are aimed at obtaining cores from all the prostatic zones and no tumor focus is specifically targeted. The major disadvantages of this technique are over detection of clinically insignificant PCa and at the same time under detection of clinically significant PCa. (Source: Seminars in Roentgenology)
