A comparison of subtraction MRI with the standard contrast-enhanced imaging in Perthes’ disease [PDF]

Journal of Children's Orthopaedics, 2019
Purpose Perthes’ disease (PD) results from loss of blood supply to the hip and can progress to femoral head deformity. MRI in the early course of the disease can provide data on the initial extent of infarct.

The use of MRI digital subtraction technique in the diagnosis of traumatic pancreatic injury

Radiology Case Reports, 2019
Traumatic pancreatic injuries are relatively uncommon in the setting of trauma, however, early detection of these injuries can alter patient management and overall prognosis. Computed tomography is the first line imaging modality in major trauma. Because

Improving Non-Cartesian MRI Reconstruction through Discontinuity Subtraction [PDF]

International Journal of Biomedical Imaging, 2006
Non-Cartesian sampling is widely used for fast magnetic resonance imaging (MRI). Accurate and fast image reconstruction from non-Cartesian k-space data becomes a challenge and gains a lot of attention.

Denoising MRI Using Spectral Subtraction [PDF]

IEEE Transactions on Biomedical Engineering, 2013
Improving the signal-to-noise-ratio (SNR) of magnetic resonance imaging (MRI) using denoising techniques could enhance their value, provided that signal statistics and image resolution are not compromised. Here, a new denoising method based on spectral subtraction of the measured noise power from each signal acquisition is presented.

Value of Dynamic Subtraction MRI in Assessing HCC Response to Image-guided loco-regional Therapy [PDF]

African Journal of Gastroenterology and Hepatology, 2023
Background: Hepatocellular carcinoma (HCC) is considered one of the foremost cancers worldwide. Although the hepatic resection of HCC has a high existence in the clinical scenarios, locoregional management is preferred owing to the preservation of ...

Additive role of dynamic subtraction MRI in assessment of unresolved HCC post-radiofrequency ablation

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Malignant Hepatocellular carcinoma (HCC) is one amongst the foremost widespread cancers within the world. Radiofrequency ablation (RFA) is that the most generally used substitute tool for hepatic carcinoma treatment.
