Vascular Perspectives of the Midfacial Superficial Musculoaponeurotic System.

: Presently, data on the vascularization of the superficial musculoaponeurotic system of the face (SMAS) are lacking. Thus, the present study aimed to provide new conclusive data about the topography, density, and relationship of the SMAS blood vessels with other components, namely, the fibrous connective tissue and muscles. : The study included a control lot of 42 cases from the archive of the radiology department.

Can the ADC Value Be Used as an Imaging "Biopsy" in Endometrial Cancer?

Background: The tumor histological grade is closely related to the prognosis of patients with endometrial cancer (EC). Multiparametric MRI, including diffusion-weighted imaging (DWI), provides information about the cellular density that may be useful to differentiate between benign and malignant uterine lesions. However, correlations between apparent diffusion coefficient (ADC) values and histopathological grading in endometrial cancer remain controversial.

Morphofunctional and histological patterns of blood vessels in the superficial cervicofacial musculoaponeurotic system in midlateral face regions.

Objective: The superficial cervicofacial musculoaponeurotic system (SMAS) is a complex network formed by mimic muscles and conjunctive tissue of the superficial fascia of the face.This study aimed to introduce new anatomofunctional data on the importance of the trans-SMAS distribution pattern of the skin microperfusion of the face and to underline the role of SMAS in maintaining the homeostasis of the vascular network that crosses it. Considering the fibrous and muscular matrix of the SMAS, using COLIII and MyoH2 antibodies, together with endothelial immunohistochemistry(IHC)intercellular adhesion molecule 2 marker, we determined the correlation of these structures and their interaction.

The Diagnostic Accuracy of Pure-Tone Audiometry Screening Protocols for Vestibular Schwannoma in Patients with Asymmetrical Hearing Loss-A Systematic Review and Meta-Analysis.

(1) Background: Magnetic resonance imaging (MRI) is the gold standard investigation for all patients who present with asymmetrical hearing loss (AHL) and a high index of suspicion for vestibular schwannoma (VS). However, pure-tone audiometry (PTA) is an investigation that can be used for the screening of these patients in order to reduce the costs. The aim of this systematic review and meta-analysis was to evaluate the diagnostic accuracy of different PTA protocols for VS in patients with ASHL, when compared with MRI; (2) Methods: Medline, Embase, and Cochrane databases were used to find relevant studies.

Predicting Placenta Accreta Spectrum Disorders in a Cohort of Pregnant Patients in the North-East Region of Romania-Diagnostic Accuracy of Ultrasound and Magnetic Resonance Imaging.

In this study, we assessed the diagnostic and prognostic accuracy of the most important ultrasonographic (US) and magnetic resonance imagining (MRI) markers for PAS disorders. Material and Methods: The study included 39 adult pregnant patients with at least one previous cesarean delivery and both US and MRI investigations for placenta previa evaluated at the tertiary maternity hospital ‘Cuza Voda’, Iasi, between 2019 and 2021.

Improving the Treatment Outcome of Naso-Orbito-Ethmoido-Maxillary Fractures Using Virtual Three-Dimensional Anthropometric Data.

Background: Naso-orbito-ethmoido-maxillary (NOEM) fractures are usually the result of a high or moderate intensity impact to the upper midface. These types of fractures are difficult to treat and are frequently misdiagnosed. Craniometric analysis can be of real aid in the treatment of NOEM complex fractures by establishing midfacial proportions.

New Perspectives on Diagnosing Psoriatic Arthritis by Imaging Techniques.

Psoriatic arthritis is a chronic inflammatory condition that can lead to severe functional impairment and irreversible damage. The diagnosis can be difficult in early cases where the clinical exam is often scarce. The lack of a serological biomarker can lead to a considerable delay in diagnosis.

Extrapancreatic necrosis volume: A new tool in acute pancreatitis severity assessment?

Background: Many scores have been suggested to assess the severity of acute pancreatitis upon onset. The extrapancreatic necrosis volume is a novel, promising score that appears to be superior to other scores investigated so far.

Aim: To evaluate the discriminatory power of extrapancreatic necrosis volume to identify severe cases of acute pancreatitis.

L3 Skeletal Muscle Index Dynamics in Patients with HCV-Related Compensated Cirrhosis Following Sustained Virological Response after Direct Acting Antiviral Treatment.

: Sarcopenia is commonly associated with liver cirrhosis and predicts clinical outcome. Our aim was to identify the changes in skeletal muscle index (SMI) on computed tomography (CT) examination, as a quantitative marker of sarcopenia, in patients with HCV-related cirrhosis after direct acting antivirals (DAAs) treatment and to assess predictive factors for the evolution of SMI. This is a single center retrospective study in patients with HCV-related compensated cirrhosis who obtained sustained virological response (SVR) after DAAs.

Proposal of a Preoperative CT-Based Score to Predict the Risk of Clinically Relevant Pancreatic Fistula after Cephalic Pancreatoduodenectomy.

: Postoperative pancreatic fistula after cephalic pancreatoduodenectomy (CPD) is still the leading cause of postoperative morbidity, entailing long hospital stay and costs or even death. The aim of this study was to propose the use of morphologic parameters based on a preoperative multisequence computer tomography (CT) scan in predicting the clinically relevant postoperative pancreatic fistula (CRPF) and a risk score based on a multiple regression analysis. : For 78 consecutive patients with CPD, we measured the following parameters on the preoperative CT scans: the density of the pancreas on the unenhanced, arterial, portal and delayed phases; the unenhanced density of the liver; the caliber of the main pancreatic duct (MPD); the preoperatively estimated pancreatic remnant volume (ERPV) and the total pancreatic volume.

Predictive Value of HPV, p53, and p16 in the Post-Treatment Evolution of Malignant Tumors of the Oropharynx and Retromolar Trigone-Oropharynx Junction.

Knowledge of the interactions and influences of infectious, genetic, and environmental factors on the evolution and treatment response of malignant tumors is essential for improving the management of the disease and increasing patient survival. The objective of this study was to establish the contribution of human papillomavirus (HPV), as well as p53 and p16 tumor markers, alongside associated factors (smoking and alcohol consumption), in the progression of malignancies located in the oropharynx and at the retromolar trigone-oropharyngeal junction. We performed a prospective study including 50 patients with malignant tumors of the oropharynx and retromolar trigone-oropharyngeal junction.

Liver Remodeling on CT Examination in Patients with HCV Compensated Cirrhosis Who Achieved Sustained Virological Response after Direct-Acting Antivirals Treatment.

The purpose of this study was to assess the changes in hepatic morphology evaluated by computed tomography (CT) examination in patients with hepatitis C virus (HCV)-related compensated cirrhosis who achieved sustained virologic response (SVR) after direct-acting antivirals (DAAs) treatment. CT examination was performed in 56 patients with HCV-related compensated cirrhosis before and within 6-18 months after the treatment with Ombitasvir/Paritaprevir/ritonavir + Dasabuvir. The liver CT changes were assessed by measuring liver volume, caudate-right lobe ratio (C/RL), hepatic vessels diameters, periportal widening space, and right posterior notch.

Bacillus Calmette-Guérin therapy-associated granulomatous prostatitis mimicking prostate cancer on MRI: A case report and literature review.

Granulomatous prostatitis following bacillus Calmette-Guérin (BCG) immunotherapy is a well-known pathological entity, developing following initiation of BCG therapy as a prophylactic measure against the recurrence of non-muscle invasive bladder cancer. In addition, there are certain imaging similarities between granulomatous prostatitis and prostate cancer, including hypoechoic area on transrectal ultrasonography and low T2 signal intensity in some prostate areas on magnetic resonance imaging (MRI). This is the report of a case exhibiting a perfect imaging cross-match between granulomatous prostatitis and potential prostate cancer on repeated MRI exams, adding two supplementary aspects to the already known similarities, namely progressive restricted diffusion and increased contrast enhancement, which are specific to prostate cancer.
