This study aimed to develop a clinical-radiomics model using hyperattenuated imaging markers (HIM), characterized by hyperattenuation on head non-contrast computed tomography immediately after thrombectomy, predict the risk of hemorrhagic transformation (HT) in patients undergoing endovascular mechanical thrombectomy (MT). A total 159 consecutive with HIM were screened MT for inclusion. The datasets randomly divided into training and test cohorts at ratio 8:2. An optimal machine learning...

This study aimed to develop a predictive model integrating clinical, radiomics, and deep learning (DL) features of hyperattenuated imaging markers (HIM) from computed tomography scans immediately following mechanical thrombectomy (MT) predict hemorrhagic transformation (HT). A total 239 patients with HIM who underwent MT were enrolled, 191 (80%) in the training cohort 48 (20%) validation cohort. Additionally, was tested on an internal prospective 49 patients. 1834 radiomics 2048 DL extracted...

Follicular dendritic cell sarcoma (FDCS) is a rare malignant neoplasm of follicular cells that form tight meshwork within lymphoid follicles. It occurs most commonly in the lymph nodes and occasionally at extranodal sites, but rarely mediastinum. an under-recognized clinical entity without clear diagnosis. Due to its rarity, FDCS easily misdiagnosed by clinicians or pathologists.Herein, we report three unusual cases mediastinal FDCS, including one with hyaline vascular Castleman's disease...

To retrospectively evaluate the risk factors and clinical outcomes of bile duct injury after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) to that aid detection subsequent treatment injured duct.All patients undergoing TACE HCC were reviewed identification injury. The spectrum all analyzed including patients' demographics, laboratory data, radiologic imaging mode treatment.From January 2015 December 2017, a total 21 (4.3%) out 483 with 693 procedures...

Introduction The NICHE trial showed remarkable results of neoadjuvant immunotherapy in colorectal cancer patients with mismatch repair (MMR) deficiency (dMMR). However, rectal dMMR accounted for only 10% case. therapeutic effect is unsatisfactory MMR-proficient patients. Oxaliplatin has been demonstrated to induce immunogenic cell death (ICD), which may improve the programmed 1 blockade; however, a maximum tolerated dose required ICD. Arterial embolisation chemotherapy provides drugs locally...

Abstract Background To compare the changes in quantitative parameters and size degree of 1 8 F - fluorodeoxyglucose ([ 18 F]FDG) uptake malignant tumor lesions between Bayesian penalized-likelihood (BPL) non-BPL reconstruction algorithms. Methods Positron emission tomography/computed tomography images 86 were reconstructed using algorithms ordered subset expectation maximization (OSEM), OSEM + time flight (TOF), TOF point spread function (PSF), BPL. [ F]FDG maximum standardized value...

Dermoid cyst is a rare benign tumor exhibiting typical radiological pattern and most commonly located along the midline. Laboratory examination was always normal. However, features of some cases are atypical that can be easily misdiagnosed as other tumors.A 58-year-old patient presented with tinnitus, dizziness, blurred vision, gait unsteadiness. showed serum levels carbohydrate antigen 19-9 (CA19-9) were significantly increased (186 U/mL). A computed tomography (CT) scan revealed...

Malignant transformation of epidermoid cysts is a rare complication. Most the previously reported cases have involved postoperative malignant transformations. We present case nonpostoperative tumor into squamous cell carcinoma (SCC) that occurred in 61-year-old Chinese woman. The patient's initial cranial MRI scan showed an cyst with marginal enhancement pre-pontine cistern, and lesion gradually enlarged after 10 months. A craniotomy was performed using to remove part via right retrosigmoid...

Abstract Objective To analyze the clinical and imaging characteristics of primary ovarian lymphoma (POL) from perspective radiologists. Materials Methods The data a 52-year-old patient diagnosed with POL was retrospectively analyzed in this study. A review summary similar cases reported English over past twenty years, as available PubMed database, were also conducted. Results occurrence is not limited by age but more commonly observed forties years old. Clinical manifestations are often...

Abstract Myxoid glioneuronal tumour (MGNT), previously described as dysembryoplastic neuroepithelial of the septum pellucidum, was classified a new type in fifth edition WHO Central Nervous System Tumor Classification 2021. This classification based on its anatomical location, imaging features, and genetic characteristics. MGNTs are clinically rare prone to misdiagnosis. In this report, we present case MGNT left frontal lobe, which confirmed through surgical pathology.

Cervical aggressive fibromatosis is a rare intermediate tumor characterized by invasive growth. Aggressive (AF), also referred to as desmoid-type fibrosarcoma or grade I fibrosarcoma, clonal proliferative lesion of fibroblasts located in deep soft tissues. While many cases have been reported, there are relatively few involving the anterior inferior margin muscle space neck trapezius muscle. We present case pathologically confirmed left cervical fibromatosis, admitted Fourth Affiliated...

Through a comprehensive retrospective analysis of 52-year-old woman with primary ovarian lymphoma (POL) and review similar cases over the past decade in PubMed database, we gained several key insights into improving understanding POL among clinicians radiologists for accurate diagnosis. is more prevalent women their 40s usually presents clinical manifestations solid mass (typically 10 cm) abdominal pain B symptoms. Four imaging features show promise as indicators potential diagnostic value...

Nonfunctioning pancreatic neuroendocrine carcinoma (NPNEC) is a poorly differentiated and rare type of cancer. Computed tomography (CT)‑based imaging currently the most effective method for diagnosing classifying NPNEC. The present study investigated clinical features CT manifestations this disease. data 13 patients with NPNEC, confirmed by surgery or needle biopsy, were retrospectively analyzed. None exhibited endocrine‑related symptoms single lesion variable position in was observed all...

To evaluate the feasibility of multi-slice spiral CT scan to localize upper airway stricture in patients with obstructive sleep apnea syndrome (OSAS) during drug-induced sleeping.One hundred and fourteen diagnosed as OSAS by polysomnography were included study. Multi-slice covering was performed at end inspiration clear images obtained waking. After injecting 5 mg midazolam intravenously slowly 109 patients, sleeping. Cross-section area minimal diameter measured parameters compared under...

Objective: To determine the effect of quality control circle (QCC) activity on self-monitoring blood glucose (SMBG) in type 2diabetic patients. Design: Pre-test Post-test study. Setting: Outpatient clinic a tertiary hospital Eastern China. Subjects: A total 110 insulin-treated 2 diabetic Interventions: Quality circle.
