Arterial spin labeling imaging for the detection of cerebral blood flow asymmetry in patients with corticobasal syndrome
Corticobasal syndrome (CBS) and Parkinson’s disease (PD) both present with asymmetrical extrapyramidal symptoms, often leading to a diagnostic dilemma. Patients with CBS frequently show cerebral blood flow (CB...

Open AccessChanges in magnetic resonance imaging relaxation time on postmortem magnetic resonance imaging of formalin-fixed human normal heart tissue
Postmortem magnetic resonance imaging (MRI) has been used to investigate the cause of death, but due to time constraints, it is not widely applied to the heart. Therefore, MRI analysis of the heart after forma...

Pearls and pitfalls of imaging features of pancreatic cystic lesions: a case-based approach with imaging–pathologic correlation
A variety of neoplastic and non-neoplastic lesions of the pancreas can present with a predominantly cystic architecture. These lesions are increasingly being detected as incidental findings on routine cross-se...

Article
Primary hepatic diffuse large B-cell lymphoma presenting unusual imaging features
Primary hepatic lymphomas are frequently misdiagnosed, due to their rarity and non-specific clinical manifestations. As these tumors can be successfully treated with chemotherapy and/or radiotherapy, early rec...

Comparison of diagnostic accuracy between [18F]FDG PET/MRI and contrast-enhanced MRI in T staging for oral tongue cancer
Integrated PET/MRI with [18F]FDG is advantageous in that it enables simultaneous PET and MR imaging with higher soft-tissue contrast, multiplanar image acquisition, and functional imaging capability without using...

Article
Morphometric changes and imaging findings of diffuse liver disease in relation to intrahepatic hemodynamics
Diffuse hepatic diseases have a variety of etiologies, with each showing characteristic morphometric changes. These changes are closely related to micro- and macro-level intrahepatic hemodynamics, in addition ...

Open AccessIntegrated [18F]FDG PET/MRI demonstrates the iron-related bone-marrow physiology
We identified predictors for bone-marrow [18F]FDG uptake and MR signals among complete blood count, C-reactive protein (CRP), and anthropometric factors, and demonstrated the bone-marrow physiology using integrat...

Article
FDG-PET/CT imaging findings of hepatic tumors and tumor-like lesions based on molecular background
The usefulness of whole-body 18-fluoro-2-deoxyglucose (FDG)-fluorodeoxyglucose positron emission (PET)/computed tomography (CT) is established for assessment of disease staging, detection of early disease recu...

A case of focal confluent hepatic fibrosis in the patient with hepatitis C virus-related liver cirrhosis: a mimic of cholangiolocellular carcinoma
During routine ultrasound examination, a hyperechoic mass was detected in the anterior segment of the liver in an 80-year-old woman with hepatitis C virus-related cirrhosis. Computed tomography and magnetic re...

Article
Intravascular signal suppression and microvascular signal map** using delays alternating with nutation for tailored excitation (DANTE) pulse for arterial spin labeling perfusion imaging
To optimize the delays alternating with nutation for tailored excitation (DANTE) pulse as a vascular crushing gradient to eliminate macro-and micro-vascular signals and to generate a macrovascular space-relate...

Open AccessEvaluation of intraocular gas using magnetic resonance imaging after pars plana vitrectomy with gas tamponade for rhegmatogenous retinal detachment
We used magnetic resonance imaging (MRI) to assess how a patient’s posture affects intraocular gas changes and whether the postoperative prone position is required after pars plana vitrectomy (PPV) with gas ta...
