The potential diagnostic and prognostic value of D-dimer for AAA was assessed in this study. 1260 men from a population-based ultrasound screening study were included, of which 299 had small AAAs monitored by repeat ultrasound for a median of 5 years. 132 patients referred to a vascular clinic were also recruited, of which 41 had an AAA. The potential diagnostic and prognostic value of D-dimer ...

Deep venous thrombosis of the lower extremity poses a diagnostic challenge. Clinical signs and symptoms are often misleading, and sensitive and specific tests are essential for diagnosis. The cost, patient discomfort and risk of morbidity associated with contrast venography have led to the development of noninvasive diagnostic techniques such as Doppler ultrasound, impedance plethysmography and...

Medical diagnostic ultrasound (US) has been used by various specialties since the 1950s. Contemporary point of care ultrasound (POCUS) was first researched and utilized by emergency physicians in the mid 1980s. Emergency physicians have formally defined and pioneered POCUS during the past 2 decades. Research in a broad array of applications indicates improved patient care via procedural safety ...

Unexpected acute respiratory failure after anesthesia is a diagnostic challenge: residual neuromuscular blockade, bronchial hyperresponsiveness, laryngospasm, atelectasis, aspiration pneumonitis, and other more uncommon causes should be taken into account at diagnosis. Lung ultrasound and echocardiography are diagnostic tools that would provide the differential diagnosis. We report a suspected ...

Background:Echogenic liposomes (ELIPs) encapsulate drugs and gas bubbles within lipid vesicles. The destruction of ELIPs in response to MHz and kHz ultrasound waves has been studied previously. Applying ultrasound above a certain threshold causes encapsulated gas bubbles destruct rapidly by fragmentation or more slowly by acoustically driven diffusion. This study compares the d...

Ultrasound imaging is a widely used and safe medical diagnostic technique, due to its non-invasive nature, low cost and capability of forming real time imaging. Ultrasound imaging uses high-frequency sound to image internal structures by differing reflection signals produced when a beam of sound is projected into the body and bounces back at interfaces between the structures. However the useful...

There is a growing interest in using ultrasound diagnostic techniques for non-destructive testing of marblelstone blocks or structural elements with large sizes, in order to detect internal flaws such as cracks or fissures. Here a specific diagnostic procedure, based on ultrasound transmission measurements, is proposed. A prototype of a measuring set-up, suitable for an in-field use, is describ...

www.japi.org 897 disease.3 It is the first choice diagnostic tool especially whenever a purely diagnostic approach to the bile ducts is anticipated. In our case, though ultrasound abdomen showed cystic lesions but diagnosis of Caroli’s disease could not be firmly established and liver biopsy had to be done. The present case highlights the complementary role of ultrasound and MRCP in establishin...

Aims: Ovarian cancer has the worst prognosis among female genital tract malignancies, but if detected in the early stages, it is one of the most treatable malignancies. The aim of this study was to investigate the diagnostic value of tumor markers compared to ultrasound in the diagnosis of ovarian tumors. Materials and methods: In this cross-sectional-analytical study, 210 women referred to ...

Ultrasound (US) imaging, due to its capabilities of real-time portability, low cost and favorable safety, is frequently used as a diagnostic modality for the visualization different diseases.
