Could Cone-beam CT Demonstrate the Lateral Accessory Canals? Could Cone-beam CT Demonstrate the Lateral Accessory Canals?
Cone-beam computed tomography is being increasingly used to assess root canal morphology. Is it able to assess the full canal system, including tiny lateral and accessory canals?BMC Oral Health
CONCLUSIONS: Although PR is very helpful and widely used, CT provides more precise information on buccolingual expansion, calcification, bone septa, perforation of cortical bones and tooth resorption, features that are frequently underdescribed in the literature, particularly in OKC.

CONCLUSIONS: Using FBP, comparable IAC measurements were achieved with 91% reduction in dose compared with a standard exposure protocol. The use of ASIR and MBIR did not improve identification of the IAC in MDCT low dose images. PMID: 29791199 [PubMed - as supplied by publisher]
We thank Dr. Provencher for his valuable Editorial Commentary1 and for acknowledging our article entitled “Arthroscopic Versus Open Iliac Crest Bone Grafting in Recurrent Anterior Shoulder Instability With Glenoid Bone Loss: A Computed Tomography-Based Quantitative Assessment.”2 However, we recognized that our article may have led to some misunderstandings, which we now would like to clarify.
Iodinated contrast agents administered during computed tomography (CT) studies have the potential to cause post-contrast acute kidney injury (AKI). Prior to CT scans, in certain populations, assessment of the estimated glomerular filtration rate (eGFR) is required to identify patients at risk for adverse events after contrast administration.
Authors: Schmidt W, LiArno S, Khlopas A, Petersik A, Mont MA Abstract Due to the differences in bone morphology between demographics such as age, gender, body mass index, and ethnicity, the development of orthopaedic implants requires a large number of anatomical data from various patient populations. In an effort to assess these demographic variations, Stryker Orthopaedic Modeling and Analytics (SOMA) has been developed. SOMA is a suite of tools which utilizes a comprehensive database of computed tomography scans (CT-scans), plus associated three-dimensional (3D) bone models, allowing the user to assess population...
Conclusions De novo aneurysm of a feeder artery may form after embolization of DAVF because of hemodynamic change. It has a high risk of rupture and should be a primary consideration in embolization of DAVF. PMID: 29788813 [PubMed - as supplied by publisher]
This study aimed to understand the probability of death, given that a necropsied animal presented a specific RF. To estimate all contributions of the 48 RF, we designed a simple survey based on the Delphi method. In this survey, we invited veterinarians to evaluate the 48 NF and to assign a grade in a Likert scale from 0 to 10 for each of the RFs. In this scale, 0 (zero) indicates that the NF does not contribute to the animal's death, and 10 (ten) indicates that this NFdoes totally contributes to the animal's death. Therefore, each veterinarian, according to their own professional experience, assigns a grade describing how...
Conclusion Binimetinib may present a new treatment option for hormone- and chemotherapy-resistant LGSOC harboring KRAS mutations.
Background and Purpose—Patients with embolic large-vessel occlusion may present with additional coincidental acute occlusions within or distant from the involved territory, referred to as multivessel occlusion (MVO). Purpose of this study was to assess prevalence of MVO, associated factors, and clinical relevance in patients undergoing endovascular stroke treatment.Methods—Image data of consecutive endovascular candidates (n=720) with direct access to angiography were extracted from a prospective registry. Prevalence of MVO was assessed with multimodal magnetic resonance imaging/computed tomography and confirme...
Conclusions—A single, high-quality computed tomography angiography is the preferred diagnostic strategy. Short-term complications are rare and often transient. Long-term outcome is excellent with respect to disability and death, but high-quality studies focused at neuropsychological sequelae are needed.
