For each head CT image, we measured detection of low contrast mass lesions using a 2 Alternate Forced Choice (2-AFC) experimental paradigm. In an AFC experiment, an observer identifies the lesion location in one of two regions of interest. After performing 128 sequential observations, it is ...
The objective of this work was to evaluate the feasibility of a two-compartment distributed-parameter (DP) tracer kinetic model to generate functional images of several physiologic parameters from dynamic contrast-enhanced CT data obtained of patients with extracranial head and neck tumors and to compa...
Multi-detector row CT of the head and neck: comparison of different volumes of contrast material with and without a saline chaser. Neuroradiology 2006;48:935-42.Yoon DY, You SY, Choi CS et al (2006) Multi-detector row CT of the head and neck: comparison of different volumes of contrast...
Moreover, in contrast to generation of a fake image, which utilizes a fixed-length random vector to generate a photorealistic sample, we used ResUNet++ as backbone for the generator without adding a random vector to learn the definitive CT-to-PET mapping that increases the reproducibility. ...
Head CT images were acquired at an x-ray tube voltage of 120 kVp with a CTDIvalue of 75 mGy in a helical scan. Nine randomly selected normal images from three patients and at three anatomical head locations were reconstructed using filtered back projection (FBP) and neuro-best-contrast (NBC...
Head-to-head comparison between 18 F-FDG PET/low-dose CT and 18 F-FDG PET/contrast-enhanced CT in relapsing ovarian carcinoma: a systematic review and meta-analysis 来自 掌桥科研 喜欢 0 阅读量: 18 作者:M Massollo,G Treglia,P Trimboli,F Fiz,M Ugolini,A Piccardo ...
Whole head iodine-based contrast-enhanced computed tomography (whiceCT) In a second approach, we developed an iodine-diffusion technique to visualize the brain parenchyma with minimal shrinkage and without removing the facial skeleton. We explored the optimization of different parameters to facilitate the...
Abstract:Hypertensive intracerebral hemorrhage (HICH) is a disease with a rapid onset, rapid progression, high mortality rate, and long-term impact on the ability to function. Non-contrast agent-based CT (NCCT) is a com...
Examine patients without having to control their heart rate, with no need for them to hold their breath, and with low contrast media dose. Support quantified therapy evalutations with dose-neutral Dual Energy. See for yourself. 1/19 CT thorax to follow up bilateral pneumonia Scan time: 0.45...
To examine the added diagnostic value of emergent contrast enhanced CT head (CECTH) in patients who present to the emergency department (ED) with acute non-traumatic symptoms referable to the brain, and to assess the financial implications of CECTH in the emergent setting.We queried healthcare ...
