Purpose To analyze claustrophobia during magnetic resonance (MR) imaging and to explore the potential of the 26-item claustrophobia questionnaire (CLQ) (range, 0-4) as a screening tool in patients scheduled for MR imaging. Materials and Methods The study received institutional review board approval, and patients in the CLQ cohort provided informed consent. A total of 6520 consecutive patients were included. Overall, 4288 patients completed the CLQ before MR imaging (CLQ cohort), and 2232 patients underwent MR imaging without having completed the CLQ (non-CLQ cohort)...

Objective: Evidence indicates that behavioral or drug therapy may not target underlying pathophysiologic mechanisms for chronic insomnia, possibly due to previously unrecognized high rates (30%-90%) of sleep apnea in chronic insomnia patients. Although treatment studies with positive airway pressure (PAP) demonstrate decreased severity of chronic sleep maintenance insomnia in patients with co-occurring sleep apnea, sleep-onset insomnia has not shown similar results. We hypothesized advanced PAP technology would be associated with decreased sleep-onset insomnia severity in a sample of predominantly psychiatric patients with comorbid sleep apnea...

PURPOSE: Fetal MRI is performed without sedation. In cases of maternal claustrophobia or when reduction of fetal motion is critical, benzodiazepines may help. The purpose of this study was to evaluate the effects of low-dose benzodiazepine on fetal motion MRI and its effect on maternal oxygen levels at higher elevation. METHODS: A total of 131 fetal MRI scans performed from March 2012 through December 2013 were studied. Nineteen of the cases were performed following Valium administration...

Neuronal glycoprotein M6a belongs to the tetraspan proteolipid protein (PLP) family. Mutations in GPM6A gene have been related to mental disorders like schizophrenia, bipolar disorders and claustrophobia. M6a is expressed mainly in neuronal cells of the central nervous system and it has been extensively related to neuronal plasticity. M6a induces neuritogenesis and axon/filopodium outgrowth; however its mechanism of action is still unresolved. We recently reported that the integrity of the transmembrane domains (TMDs) 2 and 4 are critical for M6a filopodia induction...

OBJECTIVE: Besides cardiac sarcoidosis, FDG-PET is rarely used in the diagnosis of myocardial inflammation, while cardiac MRI (CMR) is the actual imaging reference for the workup of myocarditis. Using integrated PET/MRI in patients with suspected myocarditis, we prospectively compared FDG-PET to CMR and the feasibility of integrated FDG-PET/MRI in myocarditis. METHODS: A total of 65 consecutive patients with suspected myocarditis were prospectively assessed using integrated cardiac FDG-PET/MRI...

BACKGROUND: Magnetic resonance arthrogram (MRA) with radial cuts is presently the best available preoperative imaging study to evaluate chondrolabral lesions in the setting of femoroacetabular impingement (FAI). Existing followup studies for surgical treatment of FAI have evaluated predictors of treatment failure based on preoperative clinical examination, intraoperative findings, and conventional radiography. However, to our knowledge, no study has examined whether any preoperative findings on MRA images might be associated with failure of surgical treatment of FAI in the long term...

Simulated surgical environments are rapidly gaining adoption in training students, residents, and members of specialized surgical teams. However, minimal attention has been given to the use of simulated surgical environments to educate patients on surgical processes, particularly procedures that require the active participation of the patient. "Awake" neurosurgery provides a unique situation in which patients openly participate in their operation. We describe a case report, in which a 62-year-old male was referred for "awake" deep brain stimulation implantation, in relation to medically refractory Parkinson's disease...

A conventional cylindrical whole-body MRI scanner has a long bore that may cause claustrophobia for some patients in addition to being inconvenient for healthcare workers accessing the patient. A short-bore scanner usually offers a small sized imaging area, which is impractical for imaging some body parts, such as the torso. This work proposes a novel asymmetric gradient coil design that offers a full-sized imaging area close to one end of the coil. In the new design, the primary and shielding coils are connected at one end whilst separated at the other, allowing the installation of the cooling system and shim trays...

BACKGROUND: Despite differences in the information obtained by capsule endoscopy (CE) and magnetic resonance enterography (MRE), one of these modalities is usually needed when evaluating disease activity. There are no data on patients' preference that would help guide the choice between these two modalities in these instances. AIM: To compare patients' tolerance and preference to MRE versus CE. PATIENTS AND METHODS: Patients with known small bowel Crohn's disease (CD) in clinical remission (Crohn's disease activity index [CDAI] <150) or with mild symptoms (CDAI <220) were prospectively recruited...

PET/MRI is a new multimodality technique with a promising future in diagnostic imaging. Technical limitations are being overcome. Interference between the two systems (PET and MRI) seems to have been resolved. MRI-based PET attenuation correction can be performed safely. Scan time is acceptable and the study is tolerable, with claustrophobia prevalence similar to that of MRI. Quantification with common parameters, such as Standardized Uptake Value (SUV), shows a fairly good correlation between both systems...

Marco Cascella
In 1891 the Italian psychiatrist Enrico Morselli (1852-1929) described taphophobia, defining it as an extreme condition of claustrophobia due to the fear of being buried alive. This rare psychopathological phenomenon reflects an ancient fear, and its origin is not known. Taphophobia is closely linked to the problem of apparent death and premature burial. In the nineteenth century, scientists and authors paid particular attention to the issue of apparent death, and special devices (safety coffins) were invented to ensure that premature burial was avoided...

PURPOSE: Head and neck (HN) radiation therapy patients are typically immobilized with closed thermoplastic masks that cover the face and may cause discomfort. In this work, we examine the use of open masks for HN radiation therapy. METHODS AND MATERIALS: Fifty HN patients were prospectively randomized into 2 groups (25 closed masks, 25 open masks). The open-mask group was monitored with surface imaging to evaluate intrafraction motion. Both groups underwent daily volumetric imaging...

Pulmonary arterial hypertension (PAH) in adult patients with congenital heart disease (CHD) is associated with increased morbidity and mortality. The present review aims to discuss the clinical applications of invasive and non-invasive diagnostic modalities and to describe the strengths and weaknesses of each technique. Chest radiograph is an inexpensive investigation providing information on pulmonary arterial and hilar dilatation, pruning of peripheral pulmonary arteries and cardiomegaly. Transthoracic two-dimensional and Doppler echocardiography is the most widely used imaging tool...

Ventricular volumes and ejection fraction are often used in clinical decision making in patients with congenital heart disease (CHD). The referral diagnosis, radiation exposure and image quality of functional cardiac computed tomography (CT) in a relatively large cohort of patients of CHD has not been reported. This is a retrospective evaluation of functional CT studies performed in CHD patients from three institutions (1/2007-3/2013). Patient and scanner characteristics, radiation dose estimates and image quality were compared...
