Diagnostic performance of arterial spin-labeled perfusion imaging and diffusion-weighted imaging in full-term neonatal hypoxic-ischemic encephalopathy

Journal of Integrative Neuroscience, 2021
We evaluated the performance of arterial spin-labeled perfusion imaging and diffusion-weighted imaging in diagnosing full-term neonatal hypoxic-ischemic encephalopathy.

Potential use of oxygen as a metabolic biosensor in combination with T2*-weighted MRI to define the ischemic penumbra [PDF]

, 2008
We describe a novel magnetic resonance imaging technique for detecting metabolism indirectly through changes in oxyhemoglobin:deoxyhemoglobin ratios and T2* signal change during ‘oxygen challenge’ (OC, 5 mins 100% O2). During OC, T2* increase reflects O2

Combined cerebellar and bilateral cervical posterior spinal artery stroke demonstrated on MRI [PDF]

, 2003
Combined cerebellar and spinal ischemic stroke is a rare, critical condition. We report a patient with combined cerebellar and bilateral posterolateral cervical spinal cord infarction due to bilateral stenosis of the vertebral arteries. MRI is the method

Two cases of oligometastatic castration‐resistant prostate cancer detected by diffusion‐weighted whole‐body imaging with background body signal suppression

IJU Case Reports, 2020
Introduction Treatment for oligometastasis in prostate cancer has changed from systemic therapy to metastatic lesion‐targeted therapy. Early detection of metastatic lesions and assessment of the treatment response have become very important.

Hyperglycaemia does not increase perfusion deficits after focal cerebral ischaemia in male Wistar rats [PDF]

, 2018
Background: Hyperglycaemia is associated with a worse outcome in acute ischaemic stroke patients; yet the pathophysiological mechanisms of hyperglycaemia-induced damage are poorly understood.

Magnetic Resonance Imaging findings in Primary Extracutaneous Melanoma from a Tertiary Cancer Care Centre: A Retrospective Cohort Study [PDF]

Journal of Clinical and Diagnostic Research, 2022
Introduction: Extracutaneous melanomas are rare, aggressive type of tumour, clinically and biologically distinct from their cutaneous counterpart. The two large broad categories of the extracutaneous melanomas are ocular and mucosal subtypes.

Magnetic resonance imaging for localization of prostate cancer in the setting of biochemical recurrence [PDF]

, 2016
The clinical suspicion of local recurrence of prostate cancer after radical treatment is based on the onset of biochemical failure. The use of multiparametric magnetic resonance imaging (MRI) for prostate cancer has increased over recent years, mainly ...

Diffusion-Weighted Magnetic Resonance Imaging

, 2018
Magnetic resonance imaging (MRI) is a technique based on the contents and relaxation features of water in tissues. In basic MRI sequences, diffusion phenomenon of water molecules is not taken into account although it has a notable influence in the relaxation times, and therefore in the signal intensity of images.

Advances in Diffusion-Weighted Imaging [PDF]

Radiologic Clinics of North America, 2015
Diffusion-weighted imaging (DWI) has become a routine component of clinical MR imaging. Its unique soft tissue contrast mechanism exploits differences in the motion of water molecules in vivo at a biologically meaningful scale. The clinical potential of DWI in lesion detection, characterization, and response assessment has been explored.
