Computational Medical Imaging (Radiomics) and Prediction of Diffusion/FLAIR Mismatch in Stroke Patients

Stroke is a public health issue and a top priority for our organization, and it is a public health concern. The analysis of the mismatch between the DIFFUSION and FLAIR sequences, which will directly contribute to the therapeutic decision, is among the MRI findings that were reviewed in the acute phase of the stroke. It is therefore understandable that the key arterial recanalization procedures used in the acute phase are primarily reserved for patients with a positive match. Medical imaging results can now be used in conjunction with computational medical imaging methods, which have recently gained traction and can now be automated and thus more reproducible. Radiomics extracted from FLAIR imaging might also help to identify the 'diffusion flair'' mismatch in a consistent and objective manner in stroke patients. If it is found that radiomics can accurately identify the mismatch on the FLAIR sequence alone, the next step would be to make the analysis useful in clinical practice.

Laparoscopic Drainage Versus Interventional Radiology In Management Of Appendicular Abscess : A Randomized Controlled Trial.

All patients who developed appendicular absces and referred to the Zagazig University Hospital Emergency Department between January 2020 and February 2022 were included in this prospective randomized controlled clinical trial. The estimated sample size was equal to 172 patients divided into two equal groups based on the following statistics: confidence interval 95%, power of the procedure 81%, and percentage of unexposed/exposed 1, percent of patients with complications after interventional radiology's appendicular absces by interventional radiology 15%; and those managed by laparoscopy 2 %, respectively; and risk ratio 8. 7 percent, respectively; so the estimated sample size equals 172 patients divided into two separate patient samples were divided into two equal 172 patients with 172 patients divided into two equal groups; confidence intervals 172 patients with the following samples were calculated 80%, percentage of the result; confidence interval 80%; confidence interval 80%; Diagnosis After full history and thorough physical examination, appendicular absces was clinically diagnosed and later confirmed by laboratory tests, radiological imaging, and laparoscopic analysis, we excluded patients with other pathology after laparoscopic exploration However, the radiology findings were consistent with appendicular abscess. Patients were urged for drain insertion or pig catheter placement at right iliac fossa under complete sterilization by a radiologists, and after daily washing of drain or pig catheter by gentamycin & metronidazole until drain discharge is clear, with drain removing according to the amount of discharge and doing us know there is no residual, and we can say there is no residual. When one expected cell or more are less than 5, Fisher exact test was used. If one expected cell or more are less than 5, one expected cell or more are less than 5, it was used. Instead of unpaired t-test in non-parametric results, the Mann Whitney test was used instead of unpaired t-test in non-parametric results.

Pilot Study: Testing the Feasibility of a Simplified Workflow for Lung Cancer Radiation Target Review With Radiology

Primary Goals: The primary aim will be to show the tenability of radiology's real time analysis of radiation oncology therapy plans within 4 business days of the date of CT simulation, which would be the most significant goal. As a result of these changes, patients with radiation therapy plans are changed as a result of this process, determine the absolute and percentage changes in the gross tumor volume, clinical target volume, and target volume as a result of these changes. Determine if changes resulted in treatment delays for patients whose radiation therapy plans are modified as a result of this process. Using this research during diagnosis and within four weeks after therapy, determine whether acute esophagitis incidence increased in our entire sample as a result of this study's conduct during and post-treatment, as opposed to institutional historical control databases of patients treated without formal radiology review.

Implementation and Evaluation of Improved Access to Medical Imaging for Geriatric Patients of The Royal Ottawa Hospital

Visit 1: Eligibility Screening and Informed Consent The first visit will begin by exposing the study methods, investigating the inclusion and exclusion criteria, and seeking an informed consent. The Alzheimer's Disease Cooperative Study will be conducted by the participant and study partner as well as the self-rated/study partner's version of the Alzheimer's Disease Cooperative Study - Clinician's Global Impression of Change ADCS-CGIC. PET-MRI Scanning Within two weeks of the participant's referring physician will be required to complete the Mild Behaviour Checklist MBI-C. Visit 2: PET-MRI Scanning MBI-C. If the study partner is not the SDM, the SDM will need to be available by phone to review the MRI and PET safety data with the PET/MRI Technologist. To ensure that there is no competition between the PET tracer and glucose circulating in the bloodstream, a small finger prick will be done. The participant will be injected with the PET tracer by a PET Technologist 18F-fluoroglucose, 185MBq,u00b110%, followed by a 30-minute period of calm rest, eyes open to allow for tracer uptake prior to being identified in the scanner. The customer will then be positioned in the PET-MRI scanner Siemens Biograph mMR, and at 30-minutes post-injection PET results will be available for 30 minutes. A three-dimensional anatomical photograph T1 will be acquired to allow for correction of attenuation in the PET results and to place the PET images in context. FDG-PET Imaging Results After the FDG-PET scan is complete, the participant's images and medical history will be examined, and a report interpretation will be provided to the participant's referring physician. Visit 4: A 3-Month Follow-Up 3 Months After visiting Visit 3 on Wednesday, the participant, as well as the primary physician and referring physician, will be required to complete a post-scan survey. If completed at Visit 1 and study partner will be required to complete the ADCS-CGIC, the participant will be required to complete the ADCS-CGIC. DATA ANALYSIS T1 and NM-MRI results, clinical results, and MBI-C will be used to determine whether NM-MRI has the capability to provide any additional diagnostic information in the diagnosis of the participant's health. Both participant satisfaction and health surveys will be tabulated as a result of access to FDG-PET imaging.

Analysis of the Impact of Pre-procedural Consultations and Audiovisual Tools on the Patients Experience in Vascular and Interventional Radiology

For the comparison of qualitative variables, the student's t-test and the Mann-Whitney test will be used, as well as Fisher's exact test for qualitative comparisons. The expectation of results: To demonstrate that the implementation of pre-procedural consultations by interventional radiologists and the use of educational multimedia media software prior to performing Vascular and Interventional Radiology procedures enhances patient knowledge, knowledge of the procedure, and reduces the fear associated with it. It's likely that this will be the first scientific trial to examine the use of pre-procedural consultations and audiovisual equipment in Vascular and Interventional Radiology, and that the results will be very informative to help standardize clinical practice in Vascular and Interventional Radiology.

A Prospective Study to Assess the Impact of an Artificial Intelligence System on Reporting of Chest X-rays, Evaluate the Ability of AI Driven Worklists to Improve Reporting Times and Improve Same Day CT Pathway for Suspected Lung Cancer

The emergency patients' chest X-rays are obtained by the Emergency Department at Hull Royal Infirmary, but also in-patients within the hospital. Any chest X-ray performed on a patient of 16 years of age or older from one of the above sets will be immediately uploaded to the AI server, and once processed, the AI report will automatically transfer to the same PACS folder as the original film. Some basic film research will currently be outsourced, however, none of the above examinations will be outsourced and all reporting will be done by HUTH radiology team members. This will include all chest X-rays for patients over 16 years from either a GP referral or in the Emergency department of the acute hospital, which includes Accident and Emergency attendances and in-patient studies. As these are often the first examinations to raise questions regarding lung cancer, the third phase of testing the effect on the same day CT for this group has been selected, with AI-generated worklists for reporting suspected lung nodules/cancer and monitoring the impact on the same day CT for this group. The introduction of AI generated worklists in phase 3 of ED films as it was hoped that this would be the best data set to analyze the ten results obtained by the software and the introduction of AI generated worklists could result in faster reporting of abnormal findings. Readers will note that the missing data from the chest radiograph and/or AI results will be reported as normal, but not by the reporter. The reporter's impact on radiographic studies is also significant, but not significant. Not important is the most important aspect of patient care The investigators will also investigate whether AI has raised the possibility of reporting an abnormality or reporting a study as normal. Any film in which the reporter disagrees with the AI will be immediately integrated into a PACS worklist and assessed by a senior reporter/reporters and a consensus. At the end of the reporting session, the spreadsheet will be downloaded to a central Trust server, housed in a departmental folder, and linked from there to a separate database. Only members of the radiology department will have access to the departmental folder and the central database will be kept separately, only to the data manager and research team. The transition in time delay from the chest X-ray to the CT will be measured between the new device and the AI triage's radiographer triage. No personal information will be included in the assessments. Time estimates will be generated from standard data within the on the RIS and PACS systems, with no patient identifiable data being included in the analyses.
