Background: Magnetic Resonance Imaging (MRI) and Computerized Tomography (CT) Scans might be challenging for children or patients with anxiety or claustrophobia. The use of general anesthesia aims to increase the success rate, but inadequate management can result in longer length of stay. Purpose: To analyze patients' length of stay on MRI and CT-scan with intravenous anesthesia. Methods: A descriptive observational study. The datas were collected retrospectively from the medical records in General Diagnostic Center. Total of 721 patients who underwent MRI or CT Scan procedures with intravenous anesthesia during 2017-2018. The data obtained were patients' age, sex, the type of procedure, physical status, comorbid, type of anesthesia drug, diagnostic procedure duration, length of observation in the Post Anesthesia Care Unit (PACU), and overall length of stay. Results: All MRI procedures used midazolam-propofol combination, and only one CT scan procedure used this combination, while the other used only propofol. Patients undergoing MRI had length of stay with a mean duration of 6,6,3±1,26 hours, compared to CT scans with 5,20 ±1,38 hours, due to the more prolonged procedure and observation duration in the PACU. Conclusion: Patients undergoing MRI had a longer length of stay than the ones doing CT scans.

The objective of this study was to determine diagnostic accuracy of magnetic resonance imaging (MRI) and computed tomography (CT) scans in young athletes diagnosed with spondylolysis. A cross-sectional study was used. Twenty-two young athletes (14.7 ± 1.5 years) were diagnosed as spondylolysis based on a single-photon emission CT. Following the diagnosis, participants underwent MRI and CT scan imaging tests on the same day. The sensitivity and false-negative rate of the MRI and CT scans were analyzed. MRI test confirmed 13 (+) and 9 (−) results while CT test showed 17 (+) and 5 (−) results. The sensitivity and false-negative rate of MRI were, respectively, 59.1% (95% confidence interval [CI] = 36.7% to 78.5%) and 40.9% (95% CI = 21.5% to 63.3%). Furthermore, the sensitivity and false-negative rate of CT scan were 77.3% (95% CI = 54.2% to 91.3%) and 22.7% (95% CI = 0.09% to 45.8%). Our results indicated that CT scan is a more accurate imaging modality to diagnose spondylolysis compared with MRI in young athletes.

Orbital Muscles

Background: Graves’ orbitopathy (GO) is an autoimmune disease with mechanical impairment of orbital muscles and lacrimal gland dysfunction. The frequently used methods of assessing GO activity include: Clinical Activity Score (CAS), computed tomography (CT), and magnetic resonance imaging (MRI). These approaches are mainly associated with orbital muscles, however, there are not many studies that focus on the lacrimal gland inflammation of GO patients. Objective: The aim of this study is to assess the usefulness of 99mTc-DTPA SPECT/CT in evaluating the lacrimal gland inflammation in Graves orbitopathy, as compared with other methods. Methods: A retrospective analysis of 48 patients with active GO compared with 33 controls was conducted. All subjects underwent clinical-endocrinological analyses, CAS evaluation, CT scans, and SPECT/CT examination. Lacrimal gland dimensions were determined and analyzed. Results: The lacrimal glands in patients with GO were significantly larger in all measured dimensions (p < 0.001) on CT scans relative to those in controls. Increased lacrimal gland DTPA uptake ratios (p < 0.001) were displayed in active GO patients compared to controls and were also correlated with TRAb levels. The cut-off value for discriminating active and inactive disease was calculated to be 1.735, with specificity of 82.6% and sensitivity of 74.2%. SPECT/CT uptake ratios and CAS values were positively correlated in all GO patients. SPECT/CT uptake ratios were also positively correlated with CT measurements including lacrimal gland volume and coronal width in GO patients. Conclusions: These data indicated that lacrimal gland SPECT/CT images can serve as a good tool for assessing the inflammation and disease activity of GO.

Ongoing Dialogue

Twelve months ago, the Australian Medical Association (AMA) called upon the Federal Labor Government to implement a previous coalition policy allowing general practitioners to directly refer patients for magnetic resonance imaging (MRI) scans of the knee and brain. To support their position, the AMA commissioned a University of Sydney report evaluating the health care and economic outcomes of the policy. The AMA reported that the results supported the policy and would result in a $42 million saving from fewer computed tomography (CT) scans and fewer specialist referrals and consultations. Arguably, this was not an accurate portrayal of the results. Further research is needed, and ongoing dialogue with radiologists and other key stakeholders is urged, to ensure that access to MRI facilities will continue to meet future demand and that GPs will be adequately trained in utilising MRI services.

The One

In recent decades, magnetic resonance imaging (MRI) has attracted attention in radiation therapy as the only modality. This nontrivial task requires the application of pseudo computed tomography (PCT) generation methods. On the one hand, the electron density information provided by the CT scan is critical for calculating the 3D dose distribution of tissues. On the other hand, the bone image provided by the CT is precise enough for the construction of a radiograph. Lately, the use of MRI/CT has combined all of the soft tissue contrast merits which are contributed by the MRI and the virtue of CT imaging. However, owing to the unbalance of voxel-intensities in the MRI and CT scan, the MRI/CT workflow also has shortcomings. Inspired by the random forest-based PCT estimation, this paper investigated the potential of the 3D group feature as the input of the random forest regression, which is based on the 3D block-matching method, taking the correlated central voxel as the target. Four types of features including the voxel level, sub-regional level, whole cubic level with adaptive weighted conjunction and compressed level were introduced to attain the robust features. The group-based random forest regression was then utilized to obtain the approximated PCT only from corresponding MRI, and the feature is extracted from the 3D cubic MRI patches and mapped to the 3D cubic CT patch, which helps in decreasing the computation difficulty, representing the MR patches into an anatomical feature space. The alternative regression forest was used in solving the regression task for enhancing the prediction power compared with the random forest. The proposed method could efficiently capture the correlation that is observable between the CT as well as the MR images on the basis of the alternative random forest (ARF) with cubic features, and the experimental results show the performance and effectiveness of the proposed method compared with the recent learning-based and atlas-based (AB) methods

AIM: This study aimed to investigate the possible effect of intravenous anesthesia (sedation) with propofol on the levels of several cytokines (interleukin [IL]-6, IL-8, IL-10, and tumor necrosis factors-) and S100B protein in the blood plasma of children aged 1 year with craniostenosis. MATERIALS AND METHODS: Twenty patients aged 112 months diagnosed with non-syndromic forms of craniosynostosis, who underwent magnetic resonance imaging (MRI) of the brain under propofol sedation, were classified according to ASA I-II class. Peripheral blood sampling was performed before and after the drug administration, followed by laboratory analysis. RESULTS: A significant increase was found in the serum level of IL-6 (p = 0.004) when intravenous sedation with propofol was used for 29 4.93 min. CONCLUSION: Short exposure of children aged 1 year with craniostenosis to hypnotic propofol during brain MRI significantly increased the level of the pro-inflammatory cytokine IL-6 in the blood plasma.

Abstract Chronic perineal pain is an often encountered problem that is difficult to evaluate. Based on a series of 17 patients in whom urological, gynecological, and anorectal pathology was excluded, the authors compared magnetic resonance imaging (MRI) with computed tomographic (CT) scan with myelography in the investigation of chronic perineal pain. After a clinical neurological examination, patients underwent radiodiagnostic imaging of both techniques. Thirteen patients (76%) had one or more sacral meningeal cysts (MC) on MRI scan, whereas CT scan with myelography of the lumbar and sacral region revealed 7 patients (41%) with sacral MC. Sacral MC may be the etiology of chronic perineal pain in many instances, and MRI scan appears to be superior to CT scan with myelography in demonstrating sacral MC. Ten patients with sacral MC were operated on with moderate to excellent results 6 months after operation. Early postoperative results are encouraging, but further follow-up and larger series are required.

Precise Assessment

Vascular anomalies form a significant portion of congenital defects and venous malformations are the most prevalent type among adults. Multiple imaging modalities have been proposed for pre-operation assessments. Although some studies have reported Magnetic Resonance Imaging (MRI) as the most valuable modality, in many situations, CT scan remains the equipment of choice due to its availability. In each case, a precise assessment of the malformation is needed. In two cases mentioned in our study, prior to the operations, only a monophasic CT scan was performed that resulted in missing evidence of severity and extent of venous malformation. One of the imaging procedures is a three-phase CT scan. Although in the monophasic CT scans, a delay of 65 seconds is applied, in three-phase CT, both filling in and washing out are notable, which gives three-phase CT a more predictive value about flow pattern over monophasic CT.
