Ultrasound examination of the shoulder and elbow requires careful technique, appreciation of normal anatomy, and appropriate high-end equipment. Ultrasound provides detailed diagnostic information. Its accuracy is comparable to that of MRI in the assessment of the rotator cuff. Ultrasound is cheaper than MRI and is preferred by patients.

Background: Different techniques are employed to assess the endpoint of fluid therapy in hypovolemic patients. Lung ultrasound (US) is increasingly becoming a diagnostic tool critical care s...

This paper describes an infant whose cranial ultrasound scan showed marked unilateral cerebral arterial pulsation and enlargement without other abnormality. Subsequent computerized tomogram showed extensive cortical infarction in an area not readily accessed by ultrasound. It is concluded that the real time dimension of cranial ultrasound is of diagnostic value in the absence of demonstrable pa...

The presence of Internal Jugular Valves can pose a diagnostic and procedural challenge during ultrasound-guided cannulation. After ruling out dissection, thrombus, or ultrasound artifacts, it can still be accessed and successfully cannulated with appropriate precautions including use of Live ultrasound, positioning, use of soft-tipped catheters, and minimizing duration of catheter placement.

Magnetic resonance (MR)-based methods are increasingly used for liver fat quantification as a noninvasive alternative to liver biopsy in diagnostic studies, observational studies and clinical trials. Many studies have addressed the diagnostic accuracy of MR-based methods and of other noninvasive imaging methods (CT and ultrasound). Important advantages of MR-based methods over CT and ultrasound...

OBJECTIVE To create awareness of myositis ossificans (MO) as a potential complication of muscle contusion by presenting its clinical presentation and diagnostic features. An effective method of treatment is offered for those patients who develop traumatic MO. MANAGEMENT Patients in this case series developed traumatic MO, confirmed on diagnostic ultrasound. Patients participated in a treatmen...

Endoscopic ultrasound (EUS) was first introduced into medical practice in 1980s as a diagnostic imaging modality for pancreatic pathology. EUS has the unique advantage of combining ultrasound and endoscopy to obtain detailed information of the gastrointestinal tract. Over the past decade, the use of EUS in liver diseases has been increasing. EUS, which was initially used as a diagnostic tool, i...

Shakeri-Zadeh, Ph.D. Medical Physics Department, School of Medicine, Iran University of Medical Sciences (IUMS), Tehran, Iran E-mail: shakeriz@iums. ac.ir Ultrasound is an exciting theranostic modality that plays a critical role in diagnostic and treatment of various diseases [1, 2]. Owing to its non-invasive nature, acceptable safety, low cost and easy handling, ultra...

BACKGROUND The meta-analysis was performed to review the diagnostic accuracy of ultrasound reporting and data system in the diagnosis of thyroid nodules. METHODS We identified the diagnostic accuracy of ultrasound reporting and data system in 5 databases. Meta-analyses were used in selected studies to obtain pooled sensitivity, specificity, and summary receiver operating characteristic (ROC) ...

Recent efforts using perfluorocarbon (PFC) nanoparticles in conjunction with acoustic droplet vaporization has introduced the possibility of expanding the diagnostic and therapeutic capability of ultrasound contrast agents to beyond the vascular space. Our laboratories have developed phase-change nanoparticles (PCNs) from the highly volatile PFCs decafluorobutane (DFB, bp =-2 °C) and octafluoro...
