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...
非对比剂CT(non-contrast computer tomography,NCCT)能快速、准确检出HICH,其易用性及低时间成本使其成为常用诊断方法[2],对神经外科治疗决策至关重要。然而医学图像包含深层次信息进行解读解释需要很高专业知识,经验不足的阅读者最初的解...
We evaluated the impact of delayed scans on the conspicuity of squamous cell carcinoma in helical CT of the head and neck. Twenty-seven patients with biopsy-proven squamous cell carcinoma of the head and neck underwent dual-phase helical CT examinations using 100 mL of nonionic contrast material...

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 ...
Objective:To compare the diagnostic accuracy of positron emission tomography/computed tomography(PET/CT)with contrast enhanced CT(CECT)alone in the initial evaluation of cervical lymph node of patients with head and neck cancer.Methods:Fifteen consecutive patients diagnosed with a head and neck cancer ...
