Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare autosomal dominant genetic disorder of heterotopic ossification (HO) characterized by skeletal anomalies and episodic soft tissue swelling (flare-ups) that can transform into heterotopic bone. The progressive development of heterotopic bone and progressive arthropathy leads to significant limitation of mobility. This paper will review various imaging modalities used in evaluating episodic soft tissue swelling (flare-ups), heterotopic bone and skeletal anomalies...

Contrast-enhanced ultrasound (CEUS) is a specialized form of ultrasound (US) performed with an intravenous injection of microbubble contrast agents. It has been successfully used for a variety of applications including characterization of liver tumors. In April 2014, the American College of Radiology (ACR) convened a working group of international experts to develop ACR CEUS Liver Imaging Reporting and Data System (CEUS LI-RADS). An initial version of CEUS LI-RADS was published in August 2016. Although the CEUS LI-RADS concept and principles for liver lesion characterization, using dynamic contrast enhancement features, are similar to those for CT or MRI, there are significant differences between CT/MRI and CEUS LI-RADS...

CLINICAL ISSUE: Injuries of the peroneal tendons are rare and often overlooked. Typical pathologies are tendinitis, tears and dislocation. Accompanying injuries are fractures. They are often associated with instability in the ankle and rearfoot deformities; therefore, these pathologies should be excluded or taken into consideration in the treatment. The clinical examination is crucial for the diagnosis. DIAGNOSTIC WORK-UP: Ultrasound and magnetic resonance imaging (MRI) examinations are very helpful; however, the true extent of the tendon pathology is often first seen during surgery...

We report the case of a 4-year-old girl with a biochemical relapse (plasma α-fetoprotein of 57,987.6 μg/L) after hepatoblastoma and extrahepatic metastases removal and adjuvant chemotherapy. Abdominal ultrasound, CT, and MRI failed to determine the site of recurrence. F-FDG PET/CT showed increased activity in the region of left scapula and adjacent soft tissue, which was incorrectly interpreted as the postoperative repair or inflammatory change. F-DOPA PET/CT showed increased activity and noticeable progressed lesion in the same place...

Recent developments in diagnostic imaging herald a new approach to diagnosis and management of prostate cancer. Multimodality fusion that combines anatomic with functional imaging data has surpassed either of the two alone. This opens up the possibility to "find and fix" malignancy with greater accuracy than ever before. This is particularly important for prostate cancer because it is the most common male cancer in most developed countries. This article describes technical advances under investigation at our institution and others using multimodality image fusion of magnetic resonance imaging (MRI), transrectal ultrasound (TRUS), and PSMA PET/CT (defined as the combination of prostate-specific membrane antigen [PSMA], positron emission tomography [PET], and computed tomography [CT]) for personalized medicine in the diagnosis and focal therapy of prostate cancer with high-intensity focused ultrasound (HiFUS)...

Nuclear medicine imaging is widely used in pain medicine. Low back pain is commonly encountered by physicians, with its prevalence from 49% to 70%. Computed tomography (CT) or magnetic resonance imaging (MRI) are usually used to evaluate the cause of low back pain, however, these findings from these scans could also be observed in asymptomatic patients. Bone scintigraphy has an additional value in patients with low back pain. Complex regional pain syndrome (CRPS) is defined as a painful disorder of the extremities, which is characterized by sensory, autonomic, vasomotor, and trophic disturbances...

BACKGROUND: Syncope is common and approaches to establishing etiology remain a matter of clinical and financial importance. Patients often undergo comprehensive neurologic investigations despite a lack of compelling indications. The aim was to determine the prevalence of use and diagnostic yield of electroencephalography (EEG), head computed tomography (CT), head magnetic resonance imaging (MRI), and carotid Doppler ultrasound (CUS) examinations. METHODS: We conducted a systematic search in EMBASE, PubMed, and Cochrane from 1970 to 2015 for studies reporting on the use of EEG, CT, MRI, and CUS in diagnosing the cause of syncope...

In the last decades, in addition to conventional imaging techniques and magnetic resonance imaging (MRI), (18)F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) has been shown to be relevant in the detection and management of breast cancer recurrence in doubtful cases in selected groups of patients. While there are no conclusive data indicating that imaging tests, including FDG PET/CT, produce a survival benefit in asymptomatic patients, FDG PET/CT can be useful for identifying the site of relapse when traditional imaging methods are equivocal or conflicting and for identifying or confirming isolated loco-regional relapse or isolated metastatic lesions...
