injection of a bolus of contrast medium, and generated three functional images related, respectively, to intravascular circulation time (rABCT), vascular volume density (Vv) and blood-brain barrier (BBB) unidirectional constant uptake rate (Ki). This was accomplished by calculating the first ...
Sliding gantry CT With SOMATOM CT Sliding Gantry systems, you get advanced CT imaging on rails that combines exceptional scan speed for time-critical cases with advanced imaging capabilities. Seamless workflows Maquet Magnus The Maquet Magnus3 surgical table adds extraordinary flexibility to your OR, ...
This technique enabled a higher detection rate of lymph nodes using simulated images compared to the native scan alone. Theoretically, such a procedure could also increase the detection of cerebral aneurysms in a native CT scan. However, the truth-value of the calculated images could potentially ...
A recent case report demonstrated the cerebral passage of an intravenously injected bolus of 99Tc(m)O4 by means of sequential gamma camera imaging in a patient in deep drug induced coma, who subsequently recovered. In view of this problem, the authors have used over a few years portable probe...
Axial CT scan without a contrast medium was available for only one patient (case #2) and showed a round, well-circumscribed, hyperdense mass with regular margins arising from the cranial dura mater in the right temporal hemisphere (Fig. 2D). No change in the adjacent skull, dural ...
Athyroid scanandtests that determine how the thyroid is functioningmay be done. Other tests, such as use of viewing tubes to examine the nose, throat, and larynx (called nasopharyngolaryngoscopy); lungs (bronchoscopy); or esophagus (esophagoscopy) may be needed. ...
(1953) remarked "I am never sure whether I will be able to get a really satisfactory view of the whole nasopharynx". The advent of endoscopes have made the task of examination of nasopharynx simpler these days. The recent imaging modalities like CT scan and MRI has further simplified non ...
A screening CT scan is recommended if women resenting with spontaneous pneumothorax during childbearing age, recurrent pneumothorax, or bilateral pneumothorax, and the presence of TSC. Biopsy Biopsy remains the gold standard for diagnosing LAM, where the characteristic abnormal smooth muscle-like cells ca...
Do an x-ray, ultrasound, CT (computed tomography) scan, or MRI (magnetic resonance imaging) If these tests don't give a clear answer, doctors may: Do a biopsy of the lump A biopsy involves removing a small piece of tissue with a needle. Doctors then look at t...
Brain magnetic resonance (MR) showed the presence of cortical tubers. There was no ocular or heart involvement. One year later, the patient was adressed to our clinic. A new high resolution chest CT scan (HRTC) was performed, and confirmed the presence of both multiple cysts and micro...
