Verification of the Optimal Chest Compression Depth for Children in the 2015 American Heart Association Guidelines: Computed Tomography Study

This study evaluated the appropriateness of these two types by comparing their safeties in chest compression depth simulated by CT. Design: Retrospective study with data analysis conducted from January 2005 to June 2015 Setting: Regional emergency center in South Korea. Patients: Three hundred forty-nine pediatric patients 1–9 years old who had a chest CT scan. Interventions: Simulation of chest compression depths by CT. Measurements and Main Results: Internal and external anteroposterior diameter of the chest and residual internal anteroposterior diameter after simulation were measured from CT scans. The safe cutoff levels were differently applied according to age. One-third external anteroposterior diameters were compared with an upper limit of chest compression depth recommended for adults. Primary outcomes were the rates of overcompression to evaluate safety. Overcompression was defined as a negative value of residual internal anteroposterior diameter—age-specific cutoff level. Using a compression of 5-cm depth simulated by chest CT, 16% of all children (55/349) were affected by overcompression. Those 1–3 years old were affected more than those 4–9 years old (p

EMPHYSEMA QUANTIFICATION ON SIMULATED X-RAYS THROUGH DEEP LEARNING TECHNIQUES. Proc IEEE Int Symp Biomed Imaging. 2018 Apr;2018:273-276 Authors: Campo MI, Pascau J, José Estépar RS Abstract Emphysema quantification techniques rely on the use of CT scans, but they are rarely used in the diagnosis and management of patients with COPD; X-ray films are the preferred method to do this. However, this diagnosis method is very controversial, as there are not established guidelines to define the disease, sensitivity is low, and quantification cannot be done. We developed a quantification method ba...

Authors: Zhao M, Wang L, Chen J, Nie D, Cong Y, Ahmad S, Ho A, Yuan P, Fung SH, Deng HH, Xia J, Shen D Abstract Automatic segmentation of medical images finds abundant applications in clinical studies. Computed Tomography (CT) imaging plays a critical role in diagnostic and surgical planning of craniomaxillofacial (CMF) surgeries as it shows clear bony structures. However, CT imaging poses radiation risks for the subjects being scanned. Alternatively, Magnetic Resonance Imaging (MRI) is considered to be safe and provides good visualization of the soft tissues, but the bony structures appear invisible from MRI. Ther...

Conclusions: Acetabular fractures with posterior wall involvement are associated with a significantly higher rate of conversion to THA if reduction is not near-anatomic. A combination of clinical/radiographic findings is associated with poorer reductions and higher rate of conversion to THA. Level of Evidence: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Objectives: To evaluate the accuracy of reduction of the acetabular articular surface using an intraoperative computed tomography scanner (O-Arm) and screw navigation compared with a classical open technique. Design: Prospective matched cohort study. Setting: Tertiary referral center. Patients/Participants: Adult patients with acute acetabular fractures were included in the study. All patients were treated by 2 senior surgeons using intraoperative imaging and screw navigation. Main Outcome Measurements: The primary outcome measure was articular reduction. Secondary outcomes were radiation dosage, operative va...

Conclusions: The inherent anteversion of a second generation nail can be used to minimize malrotation of the femur after comminuted fractures during locked intramedullary nailing in patients with normal anteversion and is superior to our present fluoroscopic technique. Level of Evidence: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Conclusion: Long-term patient satisfaction is significantly associated with the subjective symptom severity prior to treatment, i.e., postnasal drip and overall disease severity (SNOT-22 score), but not with the objective severity of the disease (CT score and inflammation).ORL 2019;81:1 –9

Conclusion: The anatomy within the temporal bone is variable amongst CI recipients. Recorded management change and significant abnormalities occurred in both CCIP groups and across many etiologies of hearing loss patients. No specific group, based on the etiology of their hearing loss could be identified that do not require preoperative HRCT. Therefore, it is recommended that all CI patients should continue to receive preoperative HRCT imaging.

Hypothesis: The aim of this study was to present and validate the accuracy of a method to predict the required cochlear implant (CI) electrode array length for a specific angular insertion depth (AID). Background: The human cochlea exhibits remarkable interindividual morphological differences. The prediction of the required array length for a specific AID can help to improve the outcome of cochlear implant surgery. Methods: We estimated the linear insertion depth required for an angular insertion of 540 degrees using computed tomography images of 16 temporal bone specimens (eight Thiel fixed, eight formalin fixed)....

Conclusion: HFms showed atraumatic surgical insertion results with consistent mid-modiolar placement. Image fusion enhances the accuracy of the insertion trauma assessment. Routine postoperative imaging is recommended for identifying tip fold-over as well as for quality control and documentation.

Objective: To determine the feasibility of using temporal bone computed tomography (CT) scans to identify malleal ligaments and the prevalence of calcification in malleal ligaments. Study Design: Retrospective case review. CT scans were blindly and retrospectively reviewed by two physicians (a radiologist and a nonradiologist). Scans differed by slice thickness, and included both conventional CT and cone beam CT (CBCT). Setting: Ambulatory tertiary referral center. Patients: One hundred fifty-one temporal bone CT scans, obtained between the years 2014 and 2017, were initially screened, which included 302 ears. P...
