BackgroundSmall intestinal leiomyosarcoma is a rare malignant tumor of the gastrointestinal tract. Clinical symptoms are atypical and can be complicated by gastrointestinal bleeding and intestinal obstruction.Case PresentationWe report a case of a 73-year-old patient with small intestinal smooth muscle sarcoma with hepatic metastasis. No significant abnormalities were seen on examination of the abdomen. We performe Read More

BackgroundThe definition of oligometastasis is still controversial. Cytoreductive nephrectomy and metastasectomy are important approaches in selected patients with oligometastasis for improving survival. We aimed to present our laparoscopic metastasectomy experience in a rare case of contralateral adrenal metastasis in an oligometastatic kidney tumor.Case ReportA 52-year-old male patient was admitted to our clinic wi Read More

BackgroundA brain tumor is an asymmetrical expansion by cells inevitably emulating amid them. Image processing is a vibrant research area where the handing out of the image in the medical field is an exceedingly tricky field. In this paper, an expert algorithm is suggested for the detection of pituitary brain tumors from MR images.MethodsThe preprocessing techniques (smoothing, edge detection, filtering) and se Read More

BackgroundBenign multicystic peritoneal mesothelioma is a multiloculated cystic mass which originates from the peritoneum. This rare tumor is usually seen in women of childbearing age and has a high recurrence rate after surgery.Case PresentationWe present two benign multicystic peritoneal mesothelioma cases with different imaging modalities, which were also pathologically proven.ConclusionThe imaging features Read More

Gastric cancer is a malignant cancerous lesion with high morbidity and mortality. Preoperative diagnosis of gastric cancer is challenging owing to the presentation of atypical symptoms and the diversity of occurrence of focal gastric lesions. Therefore, an endoscopic biopsy is used to diagnose gastric cancer in combination with imaging examination for a comprehensive evaluation of the local tumor range (T), lymph node status Read More

Computed tomography (CT) scans are widely used to diagnose lung conditions due to their ability to provide a detailed overview of the body's respiratory system. Despite its popularity, visual examination of CT scan images can lead to misinterpretations that impede a timely diagnosis. Utilizing technology to evaluate images for disease detection is also a challenge. As a result, there is a significant demand for more adva Read More

PurposeThis study aims to compare chest computed tomography (CT) findings between adult and pediatric patients with coronavirus disease-19 (COVID-19) pneumonia.Materials and MethodsThis study included 30 pediatric patients aged 1 to 17 years and 30 adult patients over 18 years of age with COVID-19 pneumonia confirmed by reverse transcriptase-polymerase chain reaction (RT-PCR) who have findings related to CO Read More

BackgroundThe temporomandibular joint diseases have been associated with various predisposing factors. Joint spaces, articular eminence height and inclination, and the shapes of the condylar and glenoid fossa have all been shown to vary in temporomandibular joint diseases (TMD) patients. Advanced imaging techniques like cone beam computed tomography (CBCT) have been employed to estimate these parameters.Aims a Read More

IntroductionThis case report presents a discrepancy in sonographic findings between a screening sonography performed by a Sonographer in the Basic Emergency Service (BES) and a subsequent ultrasound performed by a Radiologist physician in a Referral Hospital (RH). The aim of this report is to discuss the possible reasons for the discrepancy and its implications for patient care.Case PresentationA patient with a history of ep Read More

IntroductionThe simultaneous presence of a giant intracranial meningioma and an arteriovenous malformation(AVM)in the same cerebral hemisphere is extremely rare. The treatment should be individualized depending on the case.Case PresentationA 49-year-old man presented with hemiparesis. Preoperative neuroimaging revealed a giant lesion and an AVM on the left hemisphere of the brain. Craniotomy and tumou Read More

IntroductionIn this paper, a semiautomatic image segmentation method for the serialized body slices of the Visible Human Project (VHP) is proposed.MethodsIn our method, we first verified the effectiveness of the shared matting method for the VHP slices and utilized it to segment a single image. Then, to meet the need for the automatic segmentation of serialized slice images, a method based on the parallel refinem Read More

BackgroundDeep learning (DL) can improve image quality by removing noise from accelerated MRI.ObjectiveTo compare the quality of various accelerated imaging applications in knee MRI with and without DL.MethodsWe analyzed 44 knee MRI scans from 38 adult patients using the DL-reconstructed parallel acquisition technique (PAT) between May 2021 and April 2022. The participants underwent sagittal fat-saturated T Read More

ObjectivesThe aim of this study was to examine the relationship between vertical direction differences and the nasal cavity in skeletal Class I individuals.Materials and MethodsThis study was divided into 2 groups according to the vertical direction angle, and it was conducted on a total of 60 individuals with skeletal Class I features, with 30 individuals in each subgroup. Angular and millimetric measurements (N-ANS, ANS-M Read More

BackgroundDynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is considered a promising method in lung lesion assessment.MethodsSixty-four patients with single pulmonary lesions (SPLs) received DCE-MRI at 3.0 T. Of them, 49 cases were diagnosed with lung cancer, and 15 with benign pulmonary nodules (8 inflammatory nodules, 5 tuberculosis, and 2 abscesses). SPLs were quantitatively anal Read More

IntroductionGanglion cysts are the knee’s most common benign soft tissue tumors. Ganglion cysts are seen as multiloculated fluid collections on magnetic resonance imaging (MRI), and fluid-fluid levels are not an expected finding.Case PresentationA 36-year-old female patient presented with swelling in her right knee. Magnetic resonance imaging revealed a multiseptated cyst with multiple fluid-fluid levels within the anterior of Read More

BackgroundThis study aims to reveal the relationship between lung involvement and visceral adipose tissue changes between chest-computed tomography (CT) scans taken in short intervals in COVID-19 patients.MethodsThe retrospective study included 52 patients who tested positive for SARS-CoV-2. All patients had two chest CT exams. Lung involvement measurements were calculated by using an artificial intelligence to Read More
