Production of [N]ammonia from [C]methanol on a 7.5 MeV cyclotron using C(p, n)N reaction: Detection of myocardial infarction in a mouse model.

Nkepang GN, Gali H, Houson H, Hedrick AF, Hayes B, Causey O, Inman P, Box J, Benton E, Galbraith W, Awasthi V.
Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine. 2019 Aug;150()19-24.
[N]Ammonia is commonly produced using O(p, α)N reaction but one of the limiting factor of this reaction is the relatively small nuclear cross-section at proton energies of <10 MeV. An alternative production method using C(p, n)N reaction, which has a higher nuclear cross-section at low proton ene

Independent and incremental value of ventilation/perfusion PET/CT and CT pulmonary angiography for pulmonary embolism diagnosis: results of the PECAN pilot study.

Le Roux PY, Iravani A, Callahan J, Burbury K, Eu P, Steinfort DP, Lau E, Woon B, Salaun PY, Hicks RJ, Hofman MS.
European journal of nuclear medicine and molecular imaging. 2019 Jul;46(8)1596-1604.
This pilot study assessed the independent and incremental value of Ga-V/Q PET/CT as compared with CT pulmonary angiography (CTPA) for the management of cancer patients with suspected acute pulmonary embolism (PE). All 24 cancer patients with suspected acute PE prospectively recruited underwent both

Whole-brain CT perfusion on admission predicts delayed cerebral ischemia following aneurysmal subarachnoid hemorrhage.

Dong L, Zhou Y, Wang M, Yang C, Yuan Q, Fang X.
European journal of radiology. 2019 Jul;116()165-173.
The aim of this study is to prospectively evaluate whole-brain CT perfusion (CTP) on admission to predict delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH). All 252 consecutive patients with aSAH enrolled in this study underwent one-stop whole-brain CTP scan

脳卒中 41(3), 197-202, 2019
<p>要旨：急性期虚血性脳卒中に対する血栓除去術では再灌流までの時間が重要であり，術前検査は短時間であることが望まれる．一方で大動脈解離に起因した脳神経症状を呈する症例が報告されており，これを鑑別することは安全な治療を行う上で重要である．我々は3Tesla MRI による胸部スクリーニングMRA を含めた短時間脳卒中プロトコールを169 例に試行した中で2 例の急性A 型大動脈解離を検 …
