1.
Experimental study using phantom models of cerebral aneurysms and 4D-DSA to measure blood flow on 3D-color-coded images
Fujimura S, Yamanaka Y, Kan I, Nagao M, Otani K, Karagiozov K, et al.
Technol Health Care . 2024 Jul; 32(5):3217-3230. PMID: 38968064
Background: The current 3D-iFlow application can only measure the arrival time of contrast media through intensity values. If the flow rate could be estimated by 3D-iFlow, patient-specific hemodynamics could be...

Three-dimensional fusion imaging to assess apposition of low-profile visualized intraluminal support stent for intracranial aneurysm coiling
Kato N, Ishibashi T, Otani K, Abe Y, Sano T, Nagayama G, et al.
World Neurosurg X . 2024 May; 23:100381. PMID: 38706708
Objective: To investigate on three-dimensional (3D) fusion images the apposition of low-profile visualized intraluminal support (LVIS) stents in intracranial aneurysms after treatment and assess inter-rater reliability. Materials And Methods: Records...

Virtual coil images can optimize the visualization of the neckline of intracranial aneurysms during coil embolization: A technical note
Abe Y, Ishibashi T, Otani K, Kan I, Murayama Y
Surg Neurol Int . 2023 Oct; 14:349. PMID: 37810302
Background: During coil embolization of intracranial aneurysms, the aneurysmal neck needs to be evaluated because coil protrusion into the parent artery may lead to ischemic complications. However, the neck cannot...

Hemodynamic and morphological differences in cerebral aneurysms between before and after rupture
Fujimura S, Yamanaka Y, Takao H, Ishibashi T, Otani K, Karagiozov K, et al.
J Neurosurg . 2023 Sep; 140(3):774-782. PMID: 37657114
Objective: Although it has been proposed that aneurysm morphology is different after rupture, detailed research of the morphological changes using 3D imaging acquired before and after rupture has not been...

Intraoperative Cone-Beam Computed Tomography Assessment of Spinal Pedicle Screws Placement Precision Is in Full Agreement with Postoperative Computed Tomography Assessment
Ohashi H, Kawamura D, Hatano K, Ohashi S, Tochigi S, Isoshima A, et al.
World Neurosurg . 2023 Mar; 175:e254-e263. PMID: 36966912
Objective: To assess agreement between pedicle screw placement evaluated on postoperative computed tomography (CT) and on intraoperative cone-beam CT (CBCT) and compare procedure characteristics when using first-generation and second-generation robotic...

An AI-Powered Clinical Decision Support System to Predict Flares in Rheumatoid Arthritis: A Pilot Study
Labinsky H, Ukalovic D, Hartmann F, Runft V, Wichmann A, Jakubcik J, et al.
Diagnostics (Basel) . 2023 Jan; 13(1). PMID: 36611439
Treat-to-target (T2T) is a main therapeutic strategy in rheumatology; however, patients and rheumatologists currently have little support in making the best treatment decision. Clinical decision support systems (CDSSs) could offer...

Diagnostic performance of intraoperative cone beam computed tomography compared with postoperative magnetic resonance imaging for detecting hemorrhagic transformation after endovascular treatment following large vessel occlusion
Kato N, Otani K, Abe Y, Sano T, Nagayama G, Sasaki Y, et al.
J Stroke Cerebrovasc Dis . 2022 Sep; 31(11):106790. PMID: 36156445
Objectives: Early detection of hemorrhagic transformation (HT) in patients with large vessel occlusion (LVO) after endovascular treatment is important for postoperative patient management. We investigated the diagnostic performance of intraoperative...

Visualization of extracranial-intracranial bypass in moyamoya patients using intraoperative three-dimensional digital subtraction angiography with intravenous contrast injection and robotic C-arm: patient series
Kato N, Kan I, Abe Y, Otani K, Narikiyo M, Nagayama G, et al.
J Neurosurg Case Lessons . 2022 Sep; 1(4). PMID: 36131586
Background: The authors describe a noninvasive intraoperative imaging strategy of three-dimensional (3D) digital subtraction angiography (DSA) with intravenous (IV) contrast injection, using indocyanine green (ICG) as a test bolus, during...

Intraoperative cone-beam CT with metal artifact reduction for assessment of the electrode position and the intracranial structures during deep brain stimulation procedure
Kawasaki T, Kikuchi T, Otani K, Mitsuno Y, Yamao Y, Sawamoto N, et al.
Acta Neurochir (Wien) . 2022 Jul; 164(9):2309-2316. PMID: 35851925
Background: In deep brain stimulation (DBS) for Parkinson's disease (PD), the clinical outcome largely depends on the appropriate position of the electrode implanted in the targeted structure. In intraoperative cone-beam...

Applying Machine Learning to Determine 25(OH)D Threshold Levels Using Data from the AMATERASU Vitamin D Supplementation Trial in Patients with Digestive Tract Cancer
Otani K, Kanno K, Akutsu T, Ohdaira H, Suzuki Y, Urashima M
Nutrients . 2022 May; 14(9). PMID: 35565657
Some controversy remains on thresholds for deficiency or sufficiency of serum 25-hydroxyvitamin D (25(OH)D) levels. Moreover, 25(OH)D levels sufficient for bone health might differ from those required for cancer survival....
