Background : Transvaginal ultrasound is used conventionally as initial investigation of patients with postmenopausal bleeding, but saline contrast sonohysterography is a better technique to reliably distinguish focal from diffuse endometrial lesion.

Patients and methods:     During the period from November 2011 to MAY 2012 ,40 female patients with postmenopausal bleeding were submitted to sequential examination by transvaginal ultrasound ,and sonohysterography .the presence of focal endometrial lesions and type of lesion (endometrial hyperplasia ,polyp, submucous myoma ,or malignancy )were noted .predictive values were calculated  by correlating the results with final dia

Abstract

Nowadays, the adoption of economic unity on the accuracy of financial reporting is very important. Economic units need accurate financial reporting to be more competitive and to improve the performance. Management can also achieve financial information in real time through the application of ERP systems. This system will facilitate management to access the most up-to-date information such as planning, monitoring and evaluating the business processes of the organization to be more effective.

On the practical side, the Enterprise Resource Planning (ERP) system was applied to the General Company for Vegetable Oils to demonstrate a course in enhancing the accuracy of financial reporting.

Background: Population studies suggest that 3–8% of asymptomatic adults have thyroid nodules. Nodules have a 5–15% prevalence of malignancy. Fine-needle aspiration cytology is the primary and frequently initial tool for assessing the risk of malignancy in thyroid nodules and selecting patients for thyroid surgery.
Patients and Methods: This prospective study was done during the period from June 2007 to November 2008. The study includes 141 patients with palpable solitary or multiple thyroid nodules. Only patients with normal or low TSH values were referred for ultrasound examination and ultrasound guided FNAC, which were done using fine needles (G 20).
Results: eleven patients (7.8%) have insuffici

Background: Echocardiography has an important role to follow up patients with Iatrogenic atrial septal defect (IASD) and after Catheter ablation during electro-physiological study.

Objectives: evaluating the impact of non-invasive Transthoracic Echocardiography (TTE) parameters (LAVI, LVEF, ASD size and E/e`) post radiofrequency ablation of left atrial arrhythmia.

Patients and methods: for the evaluation of the atrial septal defect, a transthoracic echocardiography (TTE) was used   in patients who underwent left atrial arrhythmia ablation, enrolled in prospective study in the Iraqi center for cardiac diseases, in cooperation with university of Baghdad /college of m

Background: Ovarian malignancy is considered to score the highest fatality among women due to lack of significant symptoms. Early diagnosis and treatment lead to good prognosis. Magnetic resonance imaging (MRI) plays a major role in the diagnosis by detecting the lesions and assessing their appearance and consistency.

Objective: To determine the accuracy of MRI in the diagnosis of ovarian malignancy and comparing this to histopathology as a gold standard test.

Patients and methods: A follow up study was conducted in the MRI unit of the Radiology Department in Baghdad Teaching Hospital / Baghdad Medical City Complex during the period from 1^st of February to 31

Recommender Systems are tools to understand the huge amount of data available in the internet world. Collaborative filtering (CF) is one of the most knowledge discovery methods used positively in recommendation system. Memory collaborative filtering emphasizes on using facts about present users to predict new things for the target user. Similarity measures are the core operations in collaborative filtering and the prediction accuracy is mostly dependent on similarity calculations. In this study, a combination of weighted parameters and traditional similarity measures are conducted to calculate relationship among users over Movie Lens data set rating matrix. The advantages and disadvantages of each measure are spotted. From the study, a n

In this research, a study is introduced on the effect of several environmental factors on the performance of an already constructed quality inspection system, which was designed using a transfer learning approach based on convolutional neural networks. The system comprised two sets of layers, transferred layers set from an already trained model (DenseNet121) and a custom classification layers set. It was designed to discriminate between damaged and undamaged helical gears according to the configuration of the gear regardless to its dimensions, and the model showed good performance discriminating between the two products at ideal conditions of high-resolution images.

So, this study aimed at testing the system performance at poor s

 Background: pedicular screw fixation is rapidly becoming a widely used method of spinal instrumentation. Despite improvement in design of instruments and surgical technique and the use of intra-operative fluoroscopy, pedicle cortical perforations occur endangering nearby neurovascular or extra vertebral structures.
Objective: This is a prospective (consecutive cases study) designed for Evaluation of incidence of pedicle screw misplacement in our study sample, compare our results to what is published in literature.
Patients and Method: This study involved 25 adult patients ( 10 males and 15 females ) their age ranged between ( 18 and 70 years) who underwent spinal surgery with pedicle screw fixation for different disorders of

Background: A number of different types of fluid may accumulate in the pleural space, the most common being transudate, exudate (thin or thick), blood and chyle. All types of pleural effusion are radio graphically identical, though historical, clinical and other radiological features may help limit the diagnostic possibilities. Sometimes, also CT and MRI can help to specify the diagnosis.
Objective: To determine the accuracy of computed tomography (CT) in enabling differentiation of pleural exudates from transudates.
Patients and methods: forty three consecutive patients (43 effusions) underwent contrast-enhanced CT. Thoracocentesis was performed to measure pleural and serum total protein values. Effusions were classified as exudat
