Comparative assessment of rest and post-stress left ventricular volumes and left ventricular ejection fraction on gated myocardial perfusion imaging (MPI) and echocardiography in patients with transient ischaemic dilation on adenosine MPI: myocardial stunning or subendocardial hypoperfusion?

TL;DR: Transient dilation of the left ventricle on adenosine MPI is not related to chamber enlargement and myocardial stunning, but is more likely a function of subendocardial hypoperfusion and impaired coronary flow reserve.

Increased activity on In-111 octreotide imaging due to radiation fibrosis.
TL;DR: A case with increased uptake resulting in a scan due to pulmonary fibrosis is presented andIndium-111 octreotide scintigraphy is presented as a useful investigation in the diagnosis and staging neuroendocrine or nonendocrine malignancies such as carcinoid, granulomas, small cell lung cancer, medullary thyroid carcinoma, and others.

Incidental Prostate-Specific Membrane Antigen Uptake in a Peripheral Nerve Sheath Tumor.
TL;DR: This case illustrates that PSma uptake can occur in a peripheral nerve sheath tumor and should be taken into consideration as a benign cause of PSMA uptake.

Progressive visual loss due to obstruction of an optic nerve sheath fenestration demonstrated on SPECT/CT radionuclide cisternography.
TL;DR: A 35-year-old woman with a 7-year history of idiopathic intracranial hypertension was referred for radionuclide cisternography after the progression of visual loss in the eyes prompted the creation of bilateral optic nerve sheath fenestration.
