The resulting T1 and T2 maps enable automated plaque segmentation in its various constituents. Additionally, the MR signal can be made sensitive to water diffusion, which can be used to map the spatial variation in the apparent diffusion coefficient (ADC) within the plaque. This is of particular...

In these cases, MRI might be helpful to distinguish between a progressive brain tumour and radiation injury. Less common is the pseudo-response, which occurs with specific treatment affecting the pathological vessels of the tumour. In pseudo-response the contrast enhancement decreases in the tumour ...
With more than 6000 PET/CT systems and approximately 250 PET/MRI systems operational worldwide, the key application of PET imaging is for oncological indications [13]. Here, [18F]FDG, an [18F]-labelled glucose analogue, is the tracer-of-choice to assess the increased glucose turnover in can...
in the schematics, typically includes X-ray imaging, Computed Tomography (CT) imaging or Ultrasound (US) or Magnetic Resonance Imaging (MRI), and, thus, yields anatomical information, which can be employed to detect, localize and describe cancerous tissue in-vivo. However, cancer is frequently ...
Intrinsic susceptibility weighted (ISW)-MRI also known as BOLD (blood oxygenation level dependent)-MRI relies on the paramagnetic properties of deoxyhaemoglobin, to generate con- trast because of the increased MR transverse relaxation rate (R2*). The technique is sensitive to pO2 within and in ...

Diagnostic work-up includes anamnesis, whole body examination, laboratory and cerebral spinal fluid (CSF) studies, magnetic resonance imaging (MRI), angiography and brain biopsy. Due to the rarity of the disease, exclusion of more frequent differential diagnoses is a key element of diagnostic work ...
MRI pattern is one of the four diagnostic criteria which are necessary for a diagnosis of definite LE according to Graus et al. [18]. Importantly, this MRI finding enables a diagnosis of definite AE in the pertinent clinical scenario even in the absence of neuronal antibodies. Conversely, in...
