Aim of the study was to investigate abnormal PM signal in MVP by using cardiac magnetic resonance imaging (MRI). Methods and Results: We enrolled 47 consecutive patients with MVP evaluated by cardiac MRI. Additional groups included healthy volunteers, patients with moderate-to-severe mitral ...
It can be hypothesized that the described complex mechanical and morphological abnormalities involving the valvular apparatus in MVP might be responsible of the altered PM signal. Interestingly, the PM dark appearance on MRI cine images is evident to the naked eye, with a very good level of ...

exhibit signal drop of liver on out-of-phase images consistent with moderate steatosis. Moderately severely increased distal esophagus enhancement is well appreciated in the interstitial phase (arrow, D). The increased enhancement is suboptimal in the arterial phase images (C). ...
A predicted group by drug interaction was noted in the dorsal medial prefrontal cortex (dmPFC) as well as right superior frontal gyrus and left and right occipital regions, such that psychosis patients showed an increased BOLD signal to LRZ challenge, rather than the decreased signal exhibited by...
11 Typically this is a result of lower impact injury.2 On MRI bone marrow edema appears as ill-defined increased signal on fluid-sensitive sequences Acute Leukemia and Lymphoma Leukemia and lymphoma represent 30% and 8% of all pediatric cancers, respectively. The bone marrow is an expected ...
Increased cell death in the cortical plate was also visible at E18.5 and P3, stages at which neuronal loss had not been previously documented in these two mutants (Fig. 4D-G and supplemental Fig. 5D,E). To test if VPS35 acts in a cell autonomous manner, we used in utero ...
This article is designed to facilitate a systematic approach to formulating a radiologic differential diagnosis based on the pattern of abnormal magnetic susceptibility on MRI. Susceptibility-weighted imaging (SWI) is a three-dimensional sequence with excellent spatial resolution and superior contrast resolut...
The presence, number, size, and localization of areas of increased signal (AIS) on T2-weighted brain MRIs obtained at 1.5 T were described and compared with findings in 71 healthy persons aged 21–50 years without diabetes, cerebrovascular or neurologic diseases. MRI was performed within 2–145...
some of these techniques referred to in the art as MRI angiography. Many such techniques are directed to measuring the signal from moving moieties (e.g., the signal from arterial blood water) in the vascular compartment, not from stationary tissue. Thus, images are based directly on water flo...
