BACKGROUND AND PURPOSE: Evaluation of shunted hydrocephalus is the most common indication for ultrafast brain MRI. Radiation-/sedation-free imaging capabilities make this protocol more desirable over CT and standard brain MRI. We hypothesized that ultrafast brain MRI can be used for selected indications beyond shunted hydrocephalus without adverse outcomes. MATERIALS AND METHODS: Ultrafast brain MRI was performed with axial, sagittal, and coronal HASTE. The radiology information system was used to identify pediatric patients (0-18 years of age) who underwent ultrafast brain MRI between March 2014 and May 2016...

OBJECTIVE: Postoperative hyperperfusion is an important complication after direct bypass for Moyamoya disease (MMD), which sometimes occurs late after initial postoperative cerebral blood flow (CBF) measurement. This study aimed to clarify the incidence of hyperperfusion with our management using postoperative continuous sedation and repeated postoperative CBF measurement, and to identify factors associated with delayed hyperperfusion. METHODS: This retrospective study evaluated 72 consecutive hemispheres in 56 adult Japanese MMD patients who underwent direct bypass...

BACKGROUND: The cornerstone of prostate cancer diagnosis remains the transrectal ultrasound-guided biopsy (TRUS-BX), which most frequently occurs in the office setting under local anesthesia. However, there are now other techniques of prostate biopsy aimed at improving outcomes such as patient comfort, significant cancer detection, and infectious complications. The purpose of the present study is to compare the cost and efficacy outcomes of five different approaches. METHODS: We compared the comprehensive costs of a random sample size of 20-30 cases from each of the following: (1) local anesthesia TRUS-BX (reference), (2) sedation TRUS-BX, (3) general anesthesia transperineal template biopsy (TP), (4) sedation MRI-TRUS fusion biopsy (FB), and (5) sedation in-bore MRI biopsy (IB-MRI)...

The lung biopsy in interstitial lung disease (ILD) represents an important diagnostic step when the clinical and radiological data are insufficient for a firm diagnosis. A growing body of evidence suggests the utility of transbronchial lung cryobiopsy (TBLC) in the diagnostic algorithm of ILD as it allows, compared to transbronchial lung biopsy with conventional forceps, a better identification of complex histological patterns - such as usual interstitial pneumonia - and can provide information which has a clinical impact on the multidisciplinary discussion similar to that provided by surgical lung biopsy...

Current radiological literature is strongly focussed on radiation imaging risks. Indeed, given there is a small but actual augment in cancer risk from exposure to ionizing radiation in children, it is important to understand what the risk of alternative techniques could be. We retrospectively review literature data concerning possible MR imaging risks, focussing on the biological effects of MR, sedation and gadolinium compound risks when dealing with infant patients. The main concerns can be summarized in: (1) Biological effects of non-ionizing electromagnetic fields (EMF) employed-whose mechanisms of interaction with human tissues are polarization, induced current, and thermal heating, respectively...

Richard B Parad
On Dec. 16, 2016, the U.S. Food and Drug Administration (FDA) released a warning regarding the potential neurotoxicity of anesthesia and sedation agents on the developing brain in children younger than 3 years and in women during their 3rd trimester of pregnancy. These concerns have relevance to the pediatric radiologist who must take into consideration how the child's state might impact image quality. In this review the author provides background on the special concerns in the potentially highest-risk group, pre-term and term neonates, and provides guidance and rationale for the avoidance of sedation in procedural imaging of the newborn...

OBJECTIVES: Despite surgical advances and effective prophylactic strategies in liver transplant, infection is still a major cause of morbidity and mortality. Up to 80% of liver recipients will develop at least 1 infection during the first year after liver transplant. The spectrum and manifestations of these infections are broad and variable. Their diagnosis and treatment are often delayed because immunosuppressive therapy diminishes inflammatory responses. However, if an infection is not identified early enough and treated properly, it can have devastating consequences...

OBJECTIVES: General anesthesia or sedation can facilitate the completion of diagnostic radiological studies in children. We evaluated the incidence, predictors, and causes of adverse events (AEs) when general anesthesia is provided for diagnostic radiological imaging. METHODS: Deidentified data from 24 pediatric tertiary care hospitals participating in the Wake-Up Safe registry during 2010-2015 were obtained for analysis. Children 18 years or younger receiving general anesthesia for radiological procedures were identified using Current Procedural Terminology codes, and reported AEs were analyzed if they were associated with anesthetic care at magnetic resonance imaging or computed tomography locations...

BACKGROUND: Radiological methods for screening, diagnostics and therapy are frequently used in healthcare. In infants and children, anaesthesia/sedation is often used in these situations to relieve the patients' perception of stress or pain. Both ionising radiation (IR) and ketamine have been shown to induce developmental neurotoxic effects and this study aimed to identify the combined effects of these in a murine model. METHODS: Male mice were exposed to a single dose of ketamine (7...

RATIONALE: Nonconvulsive status epilepticus (NCSE) is prolonged seizure activity without motor manifestations. Clinically, there are certain examination findings, in addition to elements of history, that help differentiate it from other encephalopathies. When diagnosing NCSE, the physician faces significant difficulties due to inconsistent clinical presentation and somewhat nonspecific electroencephalogram (EEG) criteria. PATIENT CONCERNS: To highlight the problems faced when dealing with such a patient, a case of a 29-year-old male who presented with an altered state of consciousness is put forth for the reader...

Gokhan Olgun, Mir Hyder Ali
BACKGROUND: Dexmedetomidine, a selective α-2 receptor agonist, can be delivered via the intranasal (IN) route and be used for procedural sedation. The drug's favorable hemodynamic profile and relative ease of application make it a promising agent for sedation during radiologic procedures, although there are few studies on its efficacy for MRI studies. METHODS: A retrospective chart review was performed between June 2014 and December 2016. Outpatients between 1 and 12 months of age who received 4 μg/kg of IN dexmedetomidine for MRI were included in the analysis...
