Background: Subarachnoid hemorrhage is cause by ruptured aneurysms. Early diagnosis is necessary for prevention of the disease. For detection of size and location of intracranial aneurysms in aneurysmal subarachnoid haemorrhage different diagnostic tool are used. The 3D DSA imaging modalities parameters were considered as gold standard in diagnosis of aneurysms. MRA and CTA competencies in diagnosis of ruptured aneurysms were also evaluated. Objective: The aim of the study was to evaluate the sensitivity of 3D DSA, CTA and MRA in diagnosis of intracranial aneurysms in referred patients. The imaging modalities parameters of 3D DSA was considered as gold standard. Study design: It was retrospective observational study with statistical approach. Methods: The 27 consecutive patients of subarachnoid haemorrhage visited the neurology and radiology department of BKMC / MMC Mardan from August 2021 to January 2022 was included in the study. All the patients passed the inclusion criteria while those who are reluctant to undergo through CTA, MRA were excluded. The three dimensional constructed images of each patient underwent through CTA, MRA and 3D DSA were recorded. The obtained data was analyzed for the results. Results: CTA and MRA has variable sensitivity range in diagnosis of intracranial aneurysms. It varied according to the size of aneurysms. For the diagnosis of small sized aneurysms the CTA and MRA has the sensitivity of 57.1 %, while it changes to 88.8 % in diagnosis of medium sized aneurysms. For diagnosis of large sized aneurysms, the CTA and MRA has same sensitivity of 100%. Hence for the detection of small and medium sized aneurysms the sensitivity of CTA and MRA reduced to 20% as compared to the sensitivity of 3D DSA. Conclusion: It was concluded from the results that the 3D DSA is most accurate tool with higher sensitivity for diagnosis of intracranial aneurysms in patients of subarachnoid haemorrhage. The results obtained by using 3D DSA are 20% more sensitive than the results obtained by using CTA and MRA.

Background: To prevent controversy, the request forms were selected to use a method of convenience sampling and also included forms from both inpatient and outpatient different department. The aim of this study whether the different request forms that were submitted to the radiological department and notice that the patients having complete information in each form of different department of radiology. Study design: This was retrospective and descriptive study. The study was carried out at the department of Radiology, MTI Mardan Medical Complex, Mardan for six months duration from May 2022 to October 2022. Methods: The total participants request form were 300 which distribute, 85 forms in CT (computated tomography), 105 forms in MRI (magnetic resonance imaging) and 110 forms in US (ultrasound image). The completeness of the data entered by the doctors was examined on the forms to avoid bias. Results: Our audit information indicate that to analysed 300 request forms were filled out just the name of patients as well as part of examination. The different category of request form included name, age, diagnosis diseases, relevant history and Dr. Name or contact number. Conclusion: The referring doctors managed to fail to fully and precisely fill out all of the disciplines. To recognize this system and communicate about how it may be done better, we suggest having discussions with radiologists and doctors from different departments.
