BACKGROUND Transcranial Doppler (TCD) has been used to estimate ICP noninvasively (nICP); however, its accuracy varies depending on different types of intracranial hypertension. Given the high specificity of TCD to detect cerebrovascular events, this study aimed to compare four TCD-based nICP methods during plateau waves of ICP. METHODS A total of 36 plateau waves were identified in 27 patien...
Introduction: Estimation of gestational age is an essential component of prenatal care. Gestational age is estimated by Last Menopausal Period, fundal height and ultrasonography. Serial measurment of fundal height and comparison with LMP predicts the G.A more accurately. Since nowadays, ultrasonography is used more frequently during pregnancy, patients have to bear more expenses. But we can u...
Hen’s native chicken reproductive organ health status evaluation is important for raising Indonesian native chicken in order to support protein supply for people demand. This study aimed to discover the images of Indonesian hen’s native chicken reproductive organ using ultrasonography. There were 18 hens that used in this study and divided into two groups, 15 hens for brightnessmode ultrasonogr...
OBJECTIVE To describe a novel algorithm, based on the new display technology 'OmniView', developed to visualize diagnostic sagittal and coronal planes of the fetal brain from volumes obtained by three-dimensional (3D) ultrasonography. METHODS We developed an algorithm to image standard neurosonographic planes by drawing dissecting lines through the axial transventricular view of 3D volume dat...
We have reviewed the literature on transcranial magnetic stimulation studies in patients with brain death, coma, vegetative, minimally conscious, and locked-in states. Transcranial magnetic stimulation permits non-invasive study of brain excitability and may extend our understanding of the underlying mechanisms of these disorders. However, use of this technique in severe brain damage remains me...
This article is part 2 of our review assessing diagnostic modalities. In the first part, we analyzed ultrasonography capabilities to detect abdominal adhesions. The second assesses effectiveness MRI and CT. CT modalities are much less commonly used in detecting adhesions than ultrasonography. has approximately same prognostic as between viscera wall, it additionally detects organs. Yet, signifi...
PURPOSE To assess the feasibility of applying trans-applicator intracavitary ultrasonography to image-guided brachytherapy for cervical cancer. MATERIAL AND METHODS For this experiment, a phantom was created and included a polyethylene tube, intended to simulate a tandem applicator, which was inserted into chicken meat and embedded in agar, along with magnetic resonance imaging (MRI)-compatib...
AIM In traumatic brain injury (TBI) patients, to overcome the secondary insults, cerebral perfusion pressure (CPP) oriented therapy is recommended. The study is assigned to estimate CPP values with middle cerebral artery (MCA) flow velocities measured noninvasively using transcranial Doppler ultrasonography (TCD). MATERIAL AND METHODS Forty-seven TBI patients were studied. Intracranial pressu...
Carotid Doppler ultrasonography is a popular tool for evaluating atherosclerosis of the carotid artery. Its two-dimensional gray scale can be used for measuring the intima-media thickness, which is very good biomarker for atherosclerosis and can aid in plaque characterization. The plaque morphology is related to the risk of stroke. The ulceration of plaque is also known as one of the strong pre...
Resuscitative ultrasonography provides rapid, repeatable, and multisystem assessment to guide diagnosis and management of critically ill patients in the emergency department (ED). Cardiac ultrasonography offers new anatomic and hemodynamic information, previously unavailable in an ED setting, whereas other applications match or exceed the speed and utility of existing tests such as chest radiog...
