There are many technical and nontechnical steps involved in a successful clinical functional MRI (fMRI) scan. The output from scanning and analysis can only be as good as the input, so task instruction and rehearsal are the most important steps during an clinical fMRI procedure. Properly pre-processed data significantly affects statistical analysis, which has a great impact on image interpretation. Even though there is general agreement on how to process clinical fMRI data, such as algorithms for head motion detection and correction, the theory and practicalities associated with data processing remain complex and constantly evolving.In 2016, the World Health Organization (WHO) central nervous system (CNS) classification scheme incorporated molecular parameters in addition to traditional microscopic features for the first time. Molecular markers add a level of objectivity that was previously missing for tumor categories heavily dependent on microscopic observation for pathologic diagnosis. This article provides a brief discussion of the major 2016 updates to the WHO CNS classification scheme and reviews typical MR imaging findings of adult primary CNS neoplasms, including diffuse infiltrating gliomas, ependymal tumors, neuronal/glioneuronal tumors, pineal gland tumors, meningiomas, nerve sheath tumors, solitary fibrous tumors, and lymphoma.Functional magnetic resonance imaging (fMRI) is useful for localizing eloquent cortex in the brain prior to neurosurgery. Language and motor paradigms offer a wide range of tasks to test brain regions within the language and motor networks. With the help of fMRI, hemispheric language dominance can be determined. It also is possible to localize specific motor and sensory areas within the motor and sensory gyri. These findings are critical for presurgical planning. The most important factor in presurgical fMRI is patient performance. Patient interview and instruction time are crucial to ensure that patients understand and comply with the fMRI paradigm.Radiographic monitoring of posttreatment glioblastoma is important for clinical trials and determining next steps in management. Evaluation for tumor progression is confounded by the presence of treatment-related radiographic changes, making a definitive determination less straight-forward. The purpose of this article was to describe imaging tools available for assessing treatment response in glioblastoma, as well as to highlight the definitions, pathophysiology, and imaging features typical of true progression, pseudoprogression, pseudoresponse, and radiation necrosis.During the past decade, functional MR imaging has rapidly moved from the research environment into clinical practice. Selleck Aristolochic acid A Preoperative functional MR imaging is now standard clinical practice not only in major academic institutions, but also in community neurosurgical and neuroradiologic practices. The clinical use of functional MR imaging will only increase in the years to come. Application of functional MR imaging (including resting-state functional MR imaging) to the context of neuropsychiatric diseases is likely to continue to advance.
The purpose of monitoring a patient treated for overactive bladder (OAB) is to ensure the effectiveness of the treatment and to detect any side effects.

To synthesize current knowledge on the follow-up and the evaluation of non-neurogenic OAB treatments.

A systematic literature review based on Pubmed, Embase, Google Scholar was conducted in June 2020.

The definition of success of OAB treatments is not consensual. Definitions of success in clinical trials usually use bladder diary data. However, they cannot always be transposed into clinical practice because they do not measure the overall effectiveness of a treatment, reported by the patient, or the satisfaction with the treatment. It is then necessary to have symptom questionnaires with an assessment of quality of life. Indeed, the concept of therapeutic success is different depending on the view of the physician or the patient. It is therefore important to carefully assess with the patient, and before initiating any treatment, the objectives and expected results of the treatment. The definition of "refractory" OAB is heterogeneous but important to select candidates for second-line treatments. Monitoring a patient with OAB is essential to adapt the treatment to efficacy and tolerance, but also to detect any change in symptoms that may reveal another urological disease.

The success or failure of OAB treatments depends on the interaction of many factors, including objective criteria measured by the clinician, and subjective criteria of perception of the treatment effectiveness by the patient.

Today, refractory overactive bladder treatment includes tibial nerve stimulation, whether percutaneously or transcutaneously, sacral neuromodulation, and botulinum toxin A detrusor injections. These conservative treatments have marginalized surgical treatments, which mainly involve supratrigonal cystectomy with augmentation cystoplasty. Several potential new treatments are being evaluated but can only be currently offered as part of clinical research protocols.

"Conservative" treatments for refractory overactive bladder have been shown to be effective. Other treatments could enrich the treatment options.

Behavioral treatments are based on bladder training and timed voiding using a bladder diary. Lifestyle modifications should be suggested. They include reduction of fluid intake, consumption of caffeine, sodas, weight loss, avoidance of acidic fruit juices and of spicy and acidic salty diet, alkalization of urine by diet and possibly, vitamin D supplementation. Pelvic floor muscle training is mainly based on manual techniques, electrostimulation and/or biofeedback. It has been shown to be effective in treating OAB. In menopausal women, local hormone therapy improves all OAB symptoms. Oral drugs include anticholinergics and beta-3-agonists. Their efficacy is quite similar and superior to placebo. In case of failure of monotherapy, they may be combined.

Apart from some lifestyle modifications, the efficacy of first-line treatments for OAB has been demonstrated by prospective controlled studies. They may be prescribed individually or in combination.

An accurate taking of history and assessment of lower urinary tract symptoms are the first steps of the evaluation of patients with OAB. In addition, the search of risk factors for OAB, the exclusion of urological causes which can be responsible for urgency and the identification of therapeutic contra-indications are essential. The clinical examination and a 3-to 7-day bladder diary are part of the initial assessment. Self-questionnaires validated in French measure patients' bother and the impact on quality of life. The urine strip or culture eliminates a urinary tract infection. Urinary cytology and cystoscopy investigate a bladder tumor in case of risk factor. The post-void residual volume has to be measured in case of voiding symptoms. Urodynamics and imaging are not first-line tests.

The understanding of the initial evaluation of OAB is essential to introduce treatments adapted to patients' bother.

Women with pelvic organ prolapse very often have OAB. Prolapse surgery should be considered if the prolapse is symptomatic and never be indicated in case of overactive bladder symptoms solely. In case of symptomatic prolapse and OAB, pessary and surgical treatments are effective on both pathologies up to 71% of the cases. OAB may occur in parallel or as part of a menopausal genitourinary syndrome. In the latter case, only local estrogen therapy is effective. OAB may occur alongside stress urinary incontinence (SUI) or be integrated into mixed urinary incontinence. The initial treatment should be based on the most troublesome symptoms. In case of SUI, the outcome of surgical treatment on OAB remains uncertain. De novo, OAB follows prolapse or SUI surgery. It requires investigations to exclude urinary tract infection, bladder outlet obstruction or erosion. The treatment is the same as OAB.

The clinician's challenge is to draw a balance between the OAB and a pelvic-perineal pathology in order to adapt the treatment.

The prevalence of OAB and benign prostatic hyperplasia increases with age. Symptoms of OAB, on the one hand, and symptoms of prostatic bladder outlet obstruction, on the other hand, can be concomitant and the causal link between the two types of symptoms is difficult to establish. In case of mixed symptoms, it is recommended to treat the most troublesome type of symptoms first and to inform the patient of the risks of failure or deterioration. Indeed, many patients remain symptomatic after prostate surgery and the predictive factors for failure remain to be defined. Thus, preoperative urodynamics is not routinely performed even in case of OAB. De novo detrusor overactivity after radical prostatectomy can reach 77% and persists in the majority of cases. The overall relative risk of storage symptoms after radiotherapy and brachytherapy is higher than that after prostatectomy. The etiology of OAB after prostate surgery is multifactorial. While drug treatments have proven to be effective, little data exists on second-line treatments for OAB after prostate surgery.

OAB in men is often linked to a prostatic bladder outlet obstruction. It is essential to inform patients about the possibility of persistence, deterioration, or occurrence of OAB after prostate surgery while the predictors of surgical failure are not clearly defined.
