Overview The management of aneurysmal subarachnoid hemorrhage (aSAH) and its accompanying sequelae integrates transcranial Doppler (TCD) ultrasonography for the surveillance of the emergence and course of vasospasm (VS) and delayed cerebral ischemia. TCD surveillance of patients after aSAH has been…
Overview In 1982, Aaslid et al authored a paper with the title “Noninvasive transcranial Doppler ultrasound recording of flow velocity in basal cerebral arteries,” describing the successful insonation and blood flow velocity (FV) measurement of the basal cerebral arteries with…
Christian Doppler was born in Salzburg, Austria on November 29, 1803 and lived a short and deprived life, like many scientists of his time. In an 1842 session of the Science Section of the Royal Bohemian Society in Prague, he…
Introduction Positron emission tomography/magnetic resonance imaging (PET/MRI) is an innovative imaging technology that simultaneously acquires PET and MRI, allowing the integration of sensitive metabolic and functional information with precise structural and anatomical characterization of tissues ( ). PET/MRI has shown…

Introduction Gynecologic malignancies are a considerable source of morbidity and mortality, accounting for nearly 672,000 deaths globally in 2020 ( ). Imaging complements surgical and clinical gynecologic cancer staging. Pelvic contrast-enhanced magnetic resonance imaging (CE-MRI) is commonly used in clinical…
Introduction The use of positron emission tomography (PET) in the evaluation of genitourinary malignancies has traditionally been hampered by low tumor uptake and the masquerading effect of excreted radiopharmaceutical activity in the urinary collecting system ( ; ; ; ).…
Introduction Hybrid positron emission tomography (PET)/magnetic resonance imaging (MRI) is an emerging technology with promising applications in cancer evaluation ( ). The main advantage of these systems is that both anatomic and functional MRrI sequences are jointly acquired with metabolic…

Introduction Blood malignancies account for approximately 10% of newly diagnosed malignant tumors in the United States. While a large number of different blood cancer entities exist, three main groups are generally recognized: 1. Lymphoma, which is responsible for almost 50%…
