The Clinical Value of the Combined Detection of Enhanced CT, MRI, CEA, and CA199 in the Diagnosis of Rectal Cancer.

Background: To explore the clinical value of enhanced computed tomography (enhanced CT), magnetic resonance imaging (MRI), carcinoembryonic antigen (CEA), and cancer antigen 199 (CA199) in the diagnosis of rectal cancer (RC).

Methods: A total of 156 patients with RC confirmed by postoperative pathology admitted to the Affiliated Yantai Yuhuangding Hospital of Qingdao University from March 2018 to November 2020 were included in the malignant group, and 52 patients with chronic proctitis in the benign control group. All patients underwent preoperative enhanced CT, MRI scans, and serum CEA and CA199 tests.

Application value of MRI diffuse weighted imaging combined with PET/CT in the diagnosis of stomach cancer at different stages.

Value of MRI diffusion-weighted imaging (MRI DWI) combined with PET/CT in the diagnosis and staging of stomach cancer (SC) was investigated. A retrospective analysis was performed on 160 patients with SC diagnosed by pathological biopsy in The Affiliated Yantai Yuhuangding Hospital of Qingdao University from March 2015 to April 2018. The values of MRI DWI, PET/CT and combined diagnosis in the diagnosis and staging of SC were compared according to the criteria of diagnosis of postoperative pathological or clinical comprehensive evaluation.

Comparison of diagnostic value of multi-slice spiral CT and MRI for different pathological stages of prostate cancer.

Diagnostic value of magnetic resonance imaging (MRI) and multi-slice spiral CT (MSCT) for different pathological stages of prostate cancer was compared. A total of 112 patients with prostate cancer who underwent surgical pathology in The Affiliated Yantai Yuhuangding Hospital of Qingdao University from February 2014 to January 2016 were enrolled as prostate cancer group, and another 100 patients who received physical health examinations during the same period as the normal group. MSCT and MRI scanning were performed on patients in both groups to analyze their diagnostic value for stages A/B and C/D of prostate cancer.

Bilateral adrenal hemorrhage revealed antiphospholipid syndrome in a male patient: benefit from comprehensive treatment.

Background: Adrenal hemorrhage caused by antiphospholipid syndrome (APS) secondary to systemic lupus erythematosus (SLE) is very rare, especially in males.

Report: This study reports a 45-year-old male patient who presented with fatigue, loss of appetite, nausea, and vomiting for 2 months with a history of recurring epilepsy. On examination, he had low blood pressure (95/53 mmHg) and hyponatremia (117.

In vivo HMRS and lipidomic profiling reveals comprehensive changes of hippocampal metabolism during aging in mice.

Aging is characterized by various cellular changes in the brain. Hippocampus is important for systemic aging and lifespan control. There is still a lack of comprehensive overview of metabolic changes in hippocampus during aging.

Retrospective comparison of Computed Tomography Enterography and Magnetic Resonance Enterography in diagnosing small intestine disease.

Objective: To compare the efficacy of computed tomography enterography and magnetic resonance enterography in diagnosing small intestinal diseases.

Methods: The retrospective study comparing computed tomography enterography and magnetic resonance enterography for diagnosing diseases related to small intestine was conducted at Department of Radiology, Yantai Yuhuangding Hospital, Shandong, China, from July 2012 to February 2014. The efficacy of computed tomography enterography and magnetic resonance enterography results were evaluated for randomly-selected cases to compare the location and characteristics of small intestinal diseases together with small bowel endoscopy and clinical pathology observations.

Prospective Blinded Comparison of Computed Tomographic Enterography and Small Bowel Endoscopy in Obscure Gastrointestinal Bleeding.

Background/aims: This study investigated the value of computed tomographic enterography with new techniques, such as multi-planar reformation, curved planar reformation, and blood vessel reformation technique, in evaluation of obscure gastrointestinal bleeding by comparing computed tomographic enterography and small bowel endoscopy.

Methodology: We retrospectively evaluated 30 patients with pathologically proven obscure gastrointestinal bleeding. Patients with acute gastrointestinal bleeding were excluded.

A case of extrapancreatic solid pseudopapillary tumor in the retroperitoneum.

Solid pseudopapillary tumor (SPT) is an uncommon epithelial neoplasm of the pancreas. Very rarely it has also been described outside the pancreas. We report such a case located in the right adrenal site in a 37-year-old woman, describing the computed tomography features of the neoplasm.
