BACKGROUND: Endometriosis is a chronic gynecological inflammatory disease characterized by the presence of functional endometrial glands and stroma outside of the uterine cavity. It affects 7-10% of women of reproductive age and up to 50% of women with infertility. The current gold standard for the diagnosis combines laparoscopic evaluation and biopsy of the visualized lesions. However, laparoscopy requires general anesthesia and developed surgical skills and it has a high procedural cost...

Neurologists are frequently consulted for patients who have white matter lesions discovered incidentally on their brain MRI, performed for reasons other than suspecting a demyelinating disease. The referring physician will question if the person has multiple sclerosis (MS). If the MRI is typical for MS but there are no clinical symptoms or signs suggestive of a demyelinating disorder, patients are diagnosed as having a Radiologically Isolated Syndrome (RIS). Areas covered: This is a timely review on RIS with a focus on treatment considerations...

OBJECTIVES: Burden of cervical cancer (CC) is highest for women in low- and middle-income countries (LMICs). Human papillomavirus (HPV) is implicated as the necessary cause of CC although a number of other factors aid the long process of CC development. One among them is the presence of reproductive tract infections (RTIs). This study investigated the associations between RTIs and CC from India. METHODS: This study utilized secondary data from the Cancer Detection Centre of the ICS, Delhi...

OBJECTIVES: Mechanisms of angiogenesis regulate multiple sclerosis (MS) lesions' evolution, displaying both neuroprotective and harmful effects. Factors traditionally considered as purely angiogenic, like vascular endothelial growth factor (VEGF), exert complex heterogenous actions on both neural and vascular malformation-derived tissues. Aim of this retrospective study was to examine, for the first time, potential associations between the presence of common vascular malformations, like vertebral hemangiomas (VHs), and several clinico-radiological MS parameters...

BACKGROUND: Demyelination is a core pathological feature of multiple sclerosis (MS) and spontaneous remyelination appears to be an important mechanism for repair in the disease. Magnetization transfer ratio imaging (MTR) has been used extensively to evaluate demyelination, although limitations to its specificity are recognized. MT saturation imaging (MTsat) removes some of the T1 dependence of MTR. We have performed a comparative evaluation of MTR and MTsat imaging in a mixed group of subjects with active MS, to explore their relative sensitivity to pathology relevant to explaining clinical outcomes...

High-magnetic-field (7 T) chemical exchange saturation transfer (CEST) MRI provides information on the tissue biochemical environment. Multiple sclerosis (MS) affects the entire central nervous system, including the spinal cord. Optimal CEST saturation parameters found via simulation were implemented for CEST MRI in 10 healthy controls and 10 patients with MS, and the results were examined using traditional asymmetry analysis and a Lorentzian fitting method. In addition, T1 - and T2 *-weighted images were acquired for lesion localization and the transmitted B1 (+) field was evaluated to guide imaging parameters...

OBJECTIVE: To test a new version of the Magnetic Resonance Disease Severity Scale (v.3 = MRDSS3) for multiple sclerosis (MS), incorporating cortical gray matter lesions (CLs) from 3T magnetic resonance imaging (MRI). BACKGROUND: MRDSS1 was a cerebral MRI-defined composite scale of MS disease severity combining T2 lesion volume (T2LV), the ratio of T1 to T2LV (T1/T2), and whole brain atrophy [brain parenchymal fraction (BPF)]. MRDSS2 expanded the scale to include cerebral gray matter fraction (GMF) and upper cervical spinal cord area (UCCA)...

BACKGROUND: Loss of myelin in the spinal cord in multiple sclerosis (MS) is likely an important, and early, contributor to atrophy and associated disability. In vivo measurement of myelin is possible using myelin water fraction (MWF) imaging, but MWF has never been assessed in MS along the entire length of the spinal cord in vivo or in post-mortem tissue. OBJECTIVE: To assess the feasibility of measuring the distribution of MWF along the entire length of the spinal cord in post-mortem MS tissue using high-field MRI...

The composition of particulate emboli associated with detectable signals on transcranial Doppler (TCD) ultrasonography has previously been studied in vitro. The purpose of this investigation was to study the composition of particles associated with similar signals in patients undergoing carotid endarterectomy. We studied carotid endarterectomy specimens from four consecutive patients with internal carotid artery origin, symptomatic, severe, stenosis, and preoperative TCD showing signals that were unidirectional from the baseline, occurred throughout the cardiac cycle, lasted 25-100 ms, had intensities exceeding that of surrounding blood by at least 12 dB, and were associated with a characteristic chirping sound...

BACKGROUND AND PURPOSE: There is a paucity of literature that supports the Consortium of Multiple Sclerosis Centers guideline that proton density MR imaging is a core spinal cord sequence. We hypothesized that proton density fast spin-echo imaging is superior to T2 fast spin-echo MR imaging for the detection of cervical cord MS lesions. This study compared the detection rate and conspicuity of cervical cord MS lesions on sagittal 1.5T proton density fast spin-echo and T2 fast spin-echo MR imaging...
