Acute pancreatitis in pregnancy is a rare condition estimated to occur in 1 per 1000 to 1 per 12,000 pregnancies. The most frequent etiology in pregnancy is biliary, followed by hyperlipidemia and/or alcohol abuse. Abdominal ultrasound and endoscopic ultrasound are ideal imaging techniques for diagnosing disease because they have no radiation risk. Computed tomography, magnetic resonance cholan...
Jeong Man Cho, Kyong Tae Moon, Hyun Seung Kim, Jeong Yoon Kang, Tag Keun Yoo, Seung Wook Lee From the Department of Urology, Eulji University School of Medicine, Seoul, Korea Intratesticular varicocele is a rare entity and refers to a dilated intratesticular vein radiating from the mediastinum testis into the testicular parenchyma. A 22-year-old man was admitted to our hospital with left testic...
We have designed and built an apparatus for real-time acoustic imaging of convective flow patterns in optically opaque fluids. This apparatus takes advantage of recent advances in two-dimensional ultrasound transducer array technology; it employs a modified version of a commercially available ultrasound camera, similar to those employed in nondestructive testing of solids. Images of convection ...
Our aim is to document a case of endometrioid adenocarcinoma of the ovary found in an endometriotic cyst that was suspected on pelvic ultrasound in a patient with polycystic ovary syndrome, normal Ca125, and a recent history of ovulation induction for IVF. She underwent an exploratory laparotomy with left salpingo-oophorectomy and omental biopsies followed by reexploration, complete staging, an...
OBJECTIVE To present the frequency resonance hypothesis, a possible mechanical mechanism by which treatment with non-thermal levels of ultrasound stimulates therapeutic effects. The review encompasses a 4-decade history but focuses on recent reports describing the effects of nonthermal therapeutic levels of ultrasound at the cellular and molecular levels. DATA SOURCES A search of MEDLINE from...
desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. it has been associated with scar from previous breast surgery or trauma. especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. we presented multimodality imaging findings (ultrasound, computed tomography, magnetic ...
Physical modifications of flours are an environment-friendly technology receiving increasing attention for widening the range utilization these raw materials. Rice flour was modified with ultrasound treatments at a frequency 24 kHz and varying treatment time (2–60 min) concentration (5–30%) in dispersion. The effect modification measured flours' physical, functional, pasting rheological propert...
Initial clinical results are reported from a new real time, 2-dimensional ultrasound scanner modified for adult cephalic applications. An optimized transducer design and the use of the dynamically focused phased array imaging system have resulted in ultrasound tomograms of the brain which are significant improvements over previous attempts. Horizontal and coronal images of the ventricles, the c...
PURPOSE To report the treatment effect of interstitial brachytherapy for chest wall locoregional recurrence of breast cancer. MATERIAL AND METHODS This 44-year-old female presented with chest wall recurrence seven years after modified radical mastectomy for stage II breast cancer. Despite external beam radiation and chemotherapy, the lesion expanded as 5.3 × 5.1 × 3.0 cm(3), and 8.0 × 5.1 × 4...
Lead magnesium niobate—lead titanate (PMN-PT) single crystals have been successfully commercialized in medical ultrasound imaging. The superior properties of PMN-PT crystals over the legacy piezoelectric ceramics lead zirconate titanate (PZT) enabled ultrasound transducers with enhanced imaging (broad bandwidth and improved sensitivity). To obtain high quality and relatively low cost single cry...
