“…The choice of surgical approach must be made in multidisciplinary consultation and must be adapted to each patient and to the characteristics of each tumor (size, invasion, anal sphincter status, etc.) [14] . Lymph node dissection is not systematically performed because lymph node involvement is rare [8] .…”

Rectal gastrointestinal stromal tumors (GIST) are extremely rare, accounting for approximately 0.1% of all rectal tumors. Diagnosis is based on histological and immunohistochemical confirmation. We report the case of a 38-year-old patient with a rectal GIST revealed by chronic rectal bleeding associated with rectal tenesmus, abdominal pain with painful contractions and frequent evacuations evolving in a context of altered general state. Rectoscopy was used to visualize the tumor mass and to take biopsies; their histological and immunohistochemical study revealed a rectal location of a gastrointestinal stromal tumor. The extension assessment was negative. After discussion of the case in a multidisciplinary consultation meeting, management consisted of initially putting the patient on Imatinib given the large tumor size, the degree of local invasion and the location of the mass (lower rectum), with regular follow-up in order to schedule a less invasive surgical resection later. Despite the rarity of rectal GIST, early diagnosis is necessary to avoid progression to locoregional invasion complicating some surgical resections given the anatomical constraints of the pelvic region. Hence the interest of neoadjuvant therapy with tyrosine kinase inhibitors allowing in some cases a decrease in tumor volume, a regression of the degree of local invasion and a decrease in the morbidity of the surgery in order to improve the patient's quality of life.

“…These methods can be classified into three main families: the first family includes all the methods dedicated to the detection of myocardial borders [4][5][6]. The second family is relative to cardiac deformation monitoring approaches based on optical flow methods [7,8] third family entails the techniques of computing parametric images used to study the regional cardiac function [9][10][11][12]. In this article, we intend to present an overview of the two first approaches: the detection of myocardial borders and optical flow methods.…”

The evaluation of left ventricular wall motion in Magnetic Resonance Imaging (MRI) clinical practice is based on a visual assessment of cine-MRI sequences. In fact, clinical interpreters (radiologists) proceed with a global visual evaluation of multiple cine-MRI sequences acquired in the three standard views. In addition, some functional parameters are quantified following a manual or a semi-automatic contouring of the myocardial borders. Although these parameters give information about the functional state of the left ventricle, they are not able to provide the location and the extent of wall motion abnormalities, which are associated with many cardiovascular diseases. In the past years, several approaches were developed to overcome the limitations of the classical evaluation techniques of left ventricular function. The aim of this article is to present an overview of the different methods and to summarize the relevant techniques based on myocardial contour detection and optical flow for regional assessment of left ventricular abnormalities.
