التصوير بالرنين المغناطيسي هو وسيلة أمنة وغير مؤذية تستخدم للكشف عن كمية الحديد المتراكمة في عضلة القلب، والكبد لمرضى التلاسيميا الكبرى. تهدف هذه الرسالة إلى تقييم كل من تركيز الحديد في الكبد وفي عضلة القلب لمرضى التلاسيميا الكبرى باستخدام التصوير بالرنين المغناطيسي
MRI is a medical imaging method that does not use harmful or ionizing radiation so it is safe and can be used to measure the proportions of iron that accumulate in the organs of the human body, especially the heart and liver

The amount of digital images that are produced in hospitals is increasing rapidly. Effective
medical images can play an important role in aiding in diagnosis and treatment, they can
also be useful in the education domain for healthcare students by
explaining with these
images will help them in their studies, new trends for image retrieval using automatic
image classification has been investigated for the past few years. Medical image
Classification can play an important role in diagnostic and teaching purposes in medicine.
For these purposes different imaging modalities are used. There are many classifications
created for medical images using both grey-scale and color medical images. In this paper,
different algorithms in every step involved in medical image processing have been studied.
One way is the algorithms of preprocessing step such as Median filter [1], Histogram
equalization (HE) [2], Dynamic histogram equalization (DHE), and Contrast Limited
Adaptive Histogram Equalization (CLAHE). Second way is the Feature Selection and
Extraction step [3,4], such as Gray Level Co-occurrence Matrix(GLCM). Third way is the
classification techniques step, which is divided into three ways in this paper, first one is
texture classification techniques, second one is neural network classification techniques,
and the third one is K-Nearest Neighbor classification techniques.
In this paper, we have use MRI brain image to determine the area of tumor in brain. The
steps started by preprocessing operation to the image before inputting it to algorithm. The
image was converted to gray scale, later on remove film artifact using special algorithm,
and then remove the Skull portions from the image without effect on white and gray matter
of the brain using another algorithm, After that the image enhanced using optimized
median filter algorithm and remove Impurities that produced from first and second steps.
Mandible articulates with the cranium via the TMJ. All the components of the TMJ,
including the TMJ disc, seem to be associated with altered characteristics of the
craniofacial complex and its growth. However, the exact role of the TMJ disc thickne
ss
during the process of the facial growth is not clear yet.
Aim: The aim of this study is to investigate the association between the TMJ disc
thickness and the facial growth determined according to Jarabak in adult male subjects
with no clinical or MRI symptoms of Temporomandibular Joint Disorders.

Introduction: Liver surgery is a relatively recent and relatively major complex surgery, due
to the anatomical and histological specialty of the liver.
Objective of the research: To evaluate the results of the cases of non traumatic liver
resectio
n from November 2010 until the end of June 2017
The study included 23 patients with 61% of females and average age of 46.8 years. 30.43%
of the cases were benign lesions, while malignant lesions constituted 65.12% of all
patients. The highest percentage of lesions was of colorectal tumors with 66.66% of all
metastatic patients and 43.47% of all patients. Whereas hepatocellular carcinoma HCC
were only in 4.35% of all patients
The most common surgical procedure was segment resection. The left or right hemi
hepatectomy was in two cases, 8.7%
None of the patients had any complications which requiring a reoperation. Biliary fistula
occurred in two cases, one of which was administered conservatively, the other requiring
ERCP.
We studying in this research the reaction with Zinc sulphate in an
aqueous solution by physical - chemical method in presence of
Succinic Acid , and determined compounds which are formed in
this solution and we calculated of it formation the const
ants.
After we used these electrolytes in plating by Zinc , that is by
electro precipitation of this metal on the solid electrodes (steel,
copper) so that we definite the best of these electrolytes for galvany
and the set necessary conditions for its use.
