چکیده
larger AIF for the three correction methods: 1.Magnitude averaging (black), 2. Rician correction (red), 3. Complex averaging (green). Figure 2. Gad concentration curves converted from the AIF signals (larger ROI) using different correction methods for SNR = 1.7. The true and complex averaging curves overlap. Figure 1. The relative errors (mean±SD) of the baseline signals to the true value for the three correction methods: 1. Magnitude averaging (black), 2. Rician correction (red), 3. Complex averaging (green). Different ROI sizes for the AIF (Large ROI: 34-pixel diameter, small ROI: 5-pixel diameter) were used to demonstrate the size effect on the different methods.

متن کاملDynamic Contrast Magnetic Resonance Imaging (DCE-MRI) and Diffusion Weighted MR Imaging (DWI) for Differentiation between Benign and Malignant Salivary Gland Tumors
Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...

Objective: Measurement of blood-brain permeability dysfunction in active and chronic MS lesions with T1-weighted dynamic contrast-enhanced MRI to show variation in inflammatory activity Background: blood-brain-barrier perfusion characterization impaired in MS as some studies have shown recently buta comparison between perfusion parameters in contrast-enhanced and non-enhanced lesions not have ...
متن کاملEnhanced perfusion measurement accuracy in DCE-MRI via improved baseline signal estimation
Introduction: Dynamic contrast-enhanced (DCE-) MRI plays an increasingly important role in evaluating tumor perfusion and permeability of the microvascular wall. A spoiled gradient echo sequence is used to measure T1 changes in tumor tissue and its arterial blood supply induced by the contrast agent. However, since TR is typically much shorter than T1 of blood (~1200ms) and tumor tissues (~500-...
