Diagnosis of benign and malignant nodules with a radiomics model integrating features from nodules and mammary regions on DCE-MRI.

Objectives: To establish a radiomics model for distinguishing between the benign and malignant mammary gland nodules via combining the features from nodule and mammary regions on DCE-MRI.

Methods: In this retrospective study, a total of 103 cases with mammary gland nodules (malignant/benign = 80/23) underwent DCE-MRI, and was confirmed by biopsy pathology. Features were extracted from both nodule region and mammary region on DCE-MRI.

Significant improvement of procedural safety in stenting for basilar stenosis: A historically controlled study.

The basilar artery has the most perioperative complications in stenting compared to the other intracranial arteries. We aim to study whether the procedural safety in stenting for basilar stenosis has improved. This study was a single-arm, non-randomized trial that included historically controlled patients for comparison.

MRI radiomic features-based machine learning approach to classify ischemic stroke onset time.

Purpose: We aimed to investigate the ability of MRI radiomics features-based machine learning (ML) models to classify the time since stroke onset (TSS), which could aid in stroke assessment and treatment options.

Methods: This study involved 84 patients with acute ischemic stroke due to anterior circulation artery occlusion (51 in the training cohort and 33 in the independent test cohort). Region of infarct segmentation was manually outlined by 3D-slicer software.

Factors associated with prominent vessel sign on susceptibility-weighted imaging in acute ischemic stroke.

The prominent vessel sign (PVS) on susceptibility-weighted imaging (SWI) is not displayed in all cases of acute ischemia. We aimed to investigate the factors associated with the presence of PVS in stroke patients. Consecutive ischemic stroke patients admitted within 24 h from symptom onset underwent emergency multimodal MRI at admission.

Congenital Monocular Strabismus Fixus.

Purpose: To investigate the clinical characteristics and magnetic resonance imaging (MRI) findings of the extraocular muscle and ocular motor nerves in congenital monocular strabismus fixus.

Methods: The retrospective observational case series of three patients with congenital monocular strabismus fixus were reviewed between January 1, 2006, and December 31, 2016. Ophthalmologic examination and thin-sectioned MRI of the ocular motor nerve and the orbit were performed on the three patients.

Magnetic resonance imaging findings in sporadic Möbius syndrome.

Background: Although neuroradiological findings of Möbius syndrome have been reported as a result of brain and brainstem abnormalities, magnetic resonance imaging (MRI) now permits the direct imaging of the cranial nerve (CN) and branches in the orbits. This study presents the MRI findings in patients with sporadic Möbius syndrome.

Methods: Prospectively, CNs were imaged in the cistern using head coils and three dimensional fast imaging employing steady-state acquisition (3D-FIESTA), yielding a 0.

Vertical deviation and A pattern of type III Duane retraction syndrome.

Background: Researches in ocular electromyography (EMG) and Magnetic resonance imaging (MRI) of patients with Duane retraction syndrome (DRS) suggest that there may be additional abnormalities such as paradoxical innervation between horizontal rectus muscles and vertical rectus muscles, hypoplasia of vertical rectus muscle and that oblique muscles may also contribute to the heterogeneity of the clinical manifestation of DRS. This paper reports the results of superior rectus recession for vertical deviation and A pattern in DRS Type III and discusses the pathogenesis of the disease.

Methods: Superior and lateral rectus recession were performed in 5 cases of Huber type III DRS to treat vertical deviation and A pattern strabismus.

[Vertical retraction syndrome caused by anomalous orbital structures].

Objective: To described the clinical feature and MRI imaging of six children with vertical retraction syndrome.

Methods: Six children with unilateral vertical retraction syndrome between 15 months and 8 years of age, mean age was (5.01 ± 1.

Magnetic resonance imaging of unilateral vertical retraction syndrome with atypical strabismus.

We report two patients with unilateral vertical retraction syndrome. Magnetic resonance imaging (MRI) of the orbits of the two cases showed similar size and location of the orbital structure, but with dramatically different strabismus type. MRI sagittal reconstruction of the orbits suggested that abnormal muscle tissue arised from the inferior rectus, which might be associated with retraction and narrowing of the palpebral fissure and atypical strabismus as well.

Magnetic resonance imaging of the extraocular muscles and corresponding cranial nerves in patients with special forms of strabismus.

Background: With the technical advances, magnetic resonance imaging (MRI) is now sensitive enough to detect subtle structural abnormalities of ocular motor nerves arising from the brainstem and orbits of living subjects. This study was designed to delineate the MRI characteristics in patients with special forms of strabismus.

Methods: A total of 29 patients with special forms of strabismus underwent orbital and intracalvarium MRI.

[Magnetic resonance imaging of the ocular motor nerves in normal volunteers].

Objective: To display the detail functional anatomy of ocular motor nerves in the orbits, cavernous sinus and brainstem by high-resolution MRI.

Methods: Twenty normal subjects between 24 and 38 years of age, mean age was 28.25 +/- 4.
