Esophageal carcinoma: Intravoxel incoherent motion diffusion‐weighted MRI parameters and histopathological correlations

“…On magnetic resonance imaging (MRI) routine nonenhanced T 1 ‐weighted imaging and T 2 ‐weighted imaging can be used to evaluate the esophageal wall invasion. But both of them fail to provide a prediction of histologic grade …”

“…But both of them fail to provide a prediction of histologic grade. [10][11][12][13][14][15] Diffusion-weighted imaging (DWI) is a noninvasive approach to probe molecular diffusion of water on the microscopic scale without contrast administration, 16,17 and the diffusion of water can be quantitatively described by the apparent diffusion coefficient (ADC). Recently, a few studies have demonstrated that DWI along with ADC measurement is helpful in detecting, characterizing, and staging malignant lesions.…”

Contribution of magnetic resonance imaging to the management of esophageal diseases: A systematic review

“…MRI allowed a correct T staging in 29/32 tumors (90.6%). The accuracy was 93.8%, 90.6%, 96.9%, and 100% for diagnosing an infiltration of the mucosa, submucosa, muscularis propria, and adventitia, respectively (32). Using a 4.5-T MRI, Yamada et al studied in a similar study setting 70 esophageal squamous cell carcinomas.…”

MR fingerprinting with simultaneous T1, T2, and fat signal fraction estimation with integrated B0 correction reduces bias in water T1 and T2 estimates

“…Water T 1 , and T 2 and fat content are important for tissue characterization in MRI. For example, T 1 , and T 2 values are altered in several diseased states, such as cardiac [1,2], liver [3], muscular [4], and others [5,6], in which the affected organs may contain or be near adipose tissue. The MRI-estimated fat signal fraction (FSF) is important in studies of healthy and pathological function, including brown adipose tissue [7] and abdominal organs [8][9][10].…”
