Portable and departmental ultrasound scanning has become an increasingly utilised investigative tool in the diagnosis of puerperal complications. It must be emphasised that an understanding of the normal ultrasonographic appearance of the postpartum uterus is a prerequisite for the accurate diagnosis of puerperal pathology. This article aims to review the current understanding and application o...

Imaging of the fetal heart to diagnose congenital heart disease has become commonplace during the past 30 years, to the point that institutions such as the American College of Obstetrics and Gynecology, the American College of Radiology, and the American Institute of Ultrasound in Medicine have established, as a standard of care, routine screening for congenital heart disease in the scanning pr...

Ultrasound examination of the knee is particularly useful in the detection of synovitis, early degenerative changes within the articular cartilage of the femoral condyles, calcifications within the articular cartilage layer and menisci, bursitis, and popliteal cysts. Also, important anatomical information about the structural integrity of the supporting tissues around the knee can be obtained b...

We present two cases of pediatric patients initially presenting with a clinical suspicion of acute appendicitis. In these cases, point-of-care ultrasonography was performed early in the patient's emergency department course, leading to alternate diagnoses. This article highlights a role for point-of-care ultrasound in the diagnoses of two alternate conditions that clinically mimic appendicitis:...

More recent technological breakthroughs in diagnostic ultrasound have surpassed all expectations. With these advances, clinicians now have the tools needed to contend with many significant diagnostic challenges. However, these new technologies are so numerous and have been introduced in such rapid succession that considerable confusion surrounds their operation and application. Indeed, with the...

Although ultrasound arrays have been exploited in photoacoustic imaging to improve imaging speed, ultrasound-array-based optical-resolution photoacoustic microscopy (OR-PAM) has never been achieved previously to our knowledge. Here we present our development of multifocal OR-PAM using a microlens array for optical illumination and an ultrasound array for photoacoustic detection. Our system is c...

Ian Donald [3] was an obstetrician who developed ultrasound [4] diagnostics during the twentieth century in Europe. Ultrasound is a medical diagnostic technique that uses sound waves to produce images of the inside of the body. During the early 1900s, physicians had no way to see inside a woman?s uterus [5] during pregnancy [6]. Donald developed the first method of scanning human internal anato...

In this set of images obtained during an experimental study using a porcine animal model, we introduce ultrasound guidance of percutaneous transluminal renal angioplasty and renal stenting. A state-of-the-art intracardiac ultrasound catheter is used here for transvascular scanning from within the lumen of the abdominal aorta, thus providing a field of view for navigation of a balloon catheter a...

Nuclear imaging of the thyroid and parathyroid glands has evolved from early radionuclide rectilinear thyroid scanning to the recently developed dual isotope subtraction technique for detecting parathyroid lesions. At the same time, x-ray fluorescent scanning, ultrasound, x-ray computed tomography, and magnetic resonance imaging have improved identification of these endocrine organs. The approp...
