Superposition of lung metastases of prostate adenocarcinoma on heart as a cardiac metastases: A case report

Journal of Oncological Sciences, 2016
Background: Primary or secondary malignancies of the heart is rare and difficult to diagnosis. Most cardiac masses are detected incidentally. Positron emission tomography-computed tomography, thorax computed tomography are valuable tools for staging the ...

Fluorodeoxyglucose positron emission tomography–computed tomography in disseminated cryptococcosis

Indian Journal of Nuclear Medicine, 2017
Disseminated cryptococcosis without pulmonary involvement is a very rare phenomenon. Patterns of organ involvement in cryptococcosis resemble various other infective conditions as well as malignant conditions on fluorodeoxyglucose positron emission tomography-computed tomography.

White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Positron emission tomography-computed tomography in a case of POEMS syndrome

Indian Journal of Nuclear Medicine, 2019
The POEMS syndrome is a rare and multisystemic disease characterized by the presence of polyneuropathy, organomegaly, endocrinopathy, presence of M protein, and alterations in the skin. The existence of bone lesions is frequent, being generally blastic or mixed and rarely lytic.

A Two‐Stage Plasma Biomarker Algorithm Reduces Amyloid PET Use and the p‐Tau217 Gray Zone

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma p‐Tau217 leaves 30%–50% of patients in an indeterminate “gray zone” often requiring Aβ‐PET. We developed GRAD (Gatekeeper‐Reflex for Alzheimer's Disease), a two‐stage Aβ‐positivity prediction model to improve classification while reserving Aβ‐PET for residual uncertainty.

Associations Between Biomarkers of Alzheimer's Disease and Sleep in Cognitively Unimpaired Older Adults

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Sleep disturbances have been implicated as a risk factor for developing Alzheimer's disease (AD), but evidence linking plasma AD biomarkers to sleep in cognitively unimpaired individuals remains limited. The present study examined associations between evening, morning, and overnight changes in plasma AD biomarkers and measures of ...

Models for the PET quantitative imaging of the adenosine receptor radioligand [11C] SCH442416 in humans [PDF]

, 2010
Positron Emission Tomography is an important imaging technique, that enables regional function to be assayed in a fully quantitative and noninvasive manner. It is based on the use of radioactive tracers: [11C]SCH442416, which is the compound of interest

Iodine-123 labeled reboxetine analogues for imaging of noradrenaline transporter in brain using single photon emission computed tomography [PDF]

, 2012
Preliminary investigation of the radioiodinated (S,S)-reboxetine analogue, 123I-INER, in baboons showed this tracer to have promise for imaging the noradrenaline transporter (NAT) using single photon emission computed tomography (SPECT).
