Hace 2 días · Spectral Doppler interrogation of the portal vein (b) demonstrates intermittent bidirectional spikes (arrow in b) concerning for PVG. Subsequent Noncontrast CT of the abdomen and pelvis obtained in the sagittal ( c ) and coronal ( d ) planes was remarkable for significant colonic thickening with mesenteric stranding (arrows in c , d ) and minimal pneumatosis intestinalis (asterisk in d ...
Hace 5 días · DVT scans were performed using a default lower limb venous pre-set with a 9 MHz linear probe and a mix of spectral trace (groin), compression, and augmentation views with colour doppler. The whole leg was scanned, including the common femoral vein, femoral vein, popliteal vein, the posterior tibial and peroneal veins of the calf, and any superficial vein thrombus within five centimetres of ...
Hace 2 días · Introduction. Certain patients in the intensive care unit (ICU) are at risk for arterial insufficiency due to arterial injury (ie, aortic or other vascular dissection) or vascular surgery. Portable Doppler evaluation may also be used as an adjunct to standard blood pressure measurement or pulse detection.
Hace 5 días · Karli Trujillo. Category. Travel. Have you ever wondered why the color of an object changes as you move from one end of the visible light spectrum to the other? This phenomenon, known as a wavelength shift, is a fascinating concept in the world of science.
Hace 5 días · Colour Doppler was used to assess vascularisation, with scanning performed by two experienced dermatologists. The ultrasound equipment could scan to a depth of 1 cm providing a spatial resolution of 30 μm with all images obtained in the longitudinal view. Every lesion had B-mode and colour Doppler clips with one image extracted from each clip.
Hace 5 días · Screening for the common autosomal trisomies has been a cornerstone of obstetric care over the past 4 decades. 1,2 Although important, it is essential to recognize that aneuploidies represent only a small portion of the total fetal genetic and structural risks. Congenital malformations occur in 3–5% of births and are associated with genetic abnormalities and death. 3–5 The combination of ...
Hace 4 días · The blood flow velocity spectrum variations within the proper hepatic artery (PHA) and portal vein (PV) pre and during EECP intervention are showed in Fig. 3, which were measured in four continuous cardiac cycles based on a color Doppler ultrasound system (EPIQ7C, Philip Com, Netherlands) equipped with a 9–11 MHz multifrequency high-resolution linear probe.
