 to this paper of the presentation is the role of MRI study in evaluation of the perianal tissue line. My aims and objectives are to diagnose, evaluate perianal tissue line to determine its course extension relation to surrounding structure which aids in the pre-operative planning to study the age group gender-wise distribution, to determine the incidence of the recurrence and allowing the side effects as such like fecal incontinence to be avoided. Introduction. In a fissula there are abnormal collection between the two epithelial structures or organ or between an organ and the surface of the body. In perianal fissula abnormal collection exists between epithelial surface of analgenal perinium. MRI allows to identify the second defects or their disease extension to the perianal and supra-livator space that would be otherwise remain undetected. Perianal fissula can be primary or secondary to inflammatory bowel disease, constipation, malignancy or previous surgery etc. Discussion. Techniques for the imaging, techniques for the imaging perianal fissula on anal-steam and weighted images that provide an excellent anatomical overview of the sphincter complex, livator space, ischorectal fossa, fissula strike, inflammation, however, appear area of the dose in the intents and it cannot be distinguished from the normal structure, however T1 images are useful to discriminate between the post-operative hemorrhages from the residual track, from the residual track as the former will appear hyper-indent on non-enhanced T1 weighted images. On T2 and STER images, sphincter strike, inflammation, abscess appears as the area of hyper-indentity can be clearly distinguished from the normal tissue which appears hyper-indent. Most of our patients, whether with like perianal discharge, bloody or pleural type, perianal pain and tenderness, pleuritis, pleuritis, itching, perianal swelling, fever, constipation, bleeding with the bleeding while defecation and earning other complaints. Anatomy of the perianal muscle on MRI. Ischorectal, first of all, there is a, we have two images, first is the schematic diagram on your left and there is a MR T1 weighted images, XGL, it suggests external sphincter then inter, between external and inter, there is a inter sphincteric space, there is a ischioenal fossa, you can clearly see ischioenal fossa inter sphincteric space, inter and external sphincter. Now, there is a classification, anal clock, towards genitalia or perineal tissue, there is a 2L O clock and it towards the posterior aspect and in the sacral aspect there is a 6 O clock, when there is a 9 O clock which is the right side of the patient, 3 O clock which is the left side of the patient, the T2 weighted images of the MR, male perineal shows the anal or anal clock diagram used to correct the locate and visual as it is for respect to anal scan. There is a two classification, two classification to classify the perianal visual as according to the surgical treatment or interventional groups, first there is a inter sphincteric, trans sphincteric, suprasphincteric, extrasphincteric, external sphincteric is a keystone of the paraclassification, external sphincteric, mostly external sphincteric, once there is a trans sphincteric, you can see A is the inter sphincteric between internal sphincteric and external sphincteric, B is your trans sphincteric, E is your suprasphincteric and And D is your extra symmetry, which is extending up to the supra-liquidate space also. There is another classification, Sanjim's classification. Grade 1, grade 1 is a simple inter-synthetic specular. Grade 2 is inter-synthetic specular with absolute second ray track formation. Grade 3 is a simple trans-synthetic specular. Grade 4 is a trans-synthetic specular with absolute and secondary track formation. Grade 5 is your supra or extra-synthetic specular. Here is the inter-synthetic specular, T1 veterinary. You can clearly see which through the extra-synthetic and entering the inter-synthetic at peak proper operation. This is your trans-synthetic specular. You can clearly see an axial contrast at the T1 veterinary. Trans-synthetic specular, which is seen by error. And highly enhancing trans-synthetic specular from the dented line to the skin to an issue anal portion. NPRC to the root. There is a supra-synthetic specular. There is an extra-synthetic specular. A hyper-intensity track between perirectal and perianal from 1 o'clock to 6 o'clock. Communicating with the rectal canal at 6 o'clock position, track the same downwards to the left at an extra-synthetic force, abutting the levator and eye muscle. Grade 1 specular is a simple inter-synthetic specular. Grade 2 is an inter-synthetic specular with collection and excess formation. Simple trans-synthetic specular. Trans-synthetic specular with collection and excess formation. There is a supra, an extra-synthetic specular, which is also called as a supra-levator space. Extending into the supra-levator space. Materials. The source of the data in the patient is an STD ocular and Mdala. All the patients refer to the department of radiology and STD ocular in Mdala. We list clinical suspects or diagnosis of having perianal specular in period of July 2022, a detailed issue of regarding sex, age, sex, clinical and radiology. There are samples that this study conducted 40 clinical suspects or diagnosis of having Priscila in plain MRI studies. Age group. There is a diagnosis of having most of age group is 40 to 60 years of the age. There is a two classification and there is a path and samples and according to the most common studies is inter-synthetic Priscila and the most common grade in our study is grade 1, simple trans-inter-synthetic Priscila. The results. Out of 40 patients with clinical suspects or having the diagnosis of the perianal specular, 31 were male, 9 were female and this majority 27 belong and belongs to the 30 to 50 years of the age group. With the inter-synthetic being the most common, according to class 1 and grade 1, according to St. James conclusion, MRI has the ability today to detect Priscila associated with abscess, serine deformation, other challenging life for other radiologically modalities. In addition, there are, can provide the comprehensive images of anatomical correlation between the secondary and pelvic floor and liver tereporeal. Evaluation of clinically undetectable, significant bearing on guiding the medical therapy or surgical therapy, it can help in minimizing the recurrence and improve the pre-operative surgical planning and post-operative outcomes. This is the list of reference. Thank you so much.
