Cobalamin (Cbl) deficiency has been associated with various neuropsychiatric symptoms of different severities. While some studies dedicated in structural neuroimaging credibly address negative impact low Cbl status, functional imaging reports are limited. We herein retrospectively review the correlation Tc-99 m ethyl cysteinate dimer single-photon emission computed tomography (Tc-99 m-ECD SPECT) and clinical presentations among patients serum cobalamin status (<250 pg/ml). Twelve symptomatic...

Malignant struma ovarii is a rare disease in gynecology and the optimal treatment regimen for tumor remains obscure. We present patient who had malignant with peritoneal implants pelvic structures liver metastases shown on posttreatment iodine I-131 single-photon emission tomography (SPECT) low-dose computed (CT). The roles of ablation management are reviewed discussed.

A female patient aged 75 years presented with an incidental pulmonary nodule without FDG uptake when undergoing PET/CT. Without obtaining histologic diagnosis, the follow-up PET/CT 2 later demonstrated intense avidity within previously FDG-negative tumor. After surgery, pathologic diagnosis is lymphoepithelioma-like carcinoma (LELC). LELCs are unique because of similarities undifferentiated nasopharyngeal lymphoepithelioma and a better prognosis as compared other lung malignancies. However,...

Software-based Self-test (SBST) has been recognized as a promising complement to scan-based structural Built-in (BIST), especially for in-field self-test applications. In response the ever-increasing complexities of modern CPU designs, machine learning algorithms have proposed extract processor behavior from simulation data and help constrain ATPG generate functionally-compatible patterns. However, these simulation-based approaches in general suffer sample inefficiency, i.e., only small...

This work demonstrated the improvement of visualization lesions by modulating factors an X-ray mammography imaging system using Taguchi analysis. Optimal combinations operating in each group level combination were determined method, which all organized into only 18 groups, yielding analytical results with same confidence as if factor had been examined independently. The 4 considered machine (1) anode material (target), (2) kVp, (3) mAs and (4) field view (FOV). Each these 2 or 3 levels....

Lymph node status is pivotal in the staging process of cancer. With regards to colorectal cancer, lymph retrieval always laborious. Sometimes, it also a challenge recover minimum 12 nodes from pericolorectal tissue. Among many proposed adjunctive solutions, GEWF solution (glacial acetic acid, ethanol, distilled water, and formaldehyde) has been introduced recently suggested be superior. To further evaluate its efficiency, tissue, which reexamined extensively conventional condition, was...

This study examined the feasibility of quantitatively evaluating multiple biokinetic models and established validity different compartment using an assembled water phantom. Most commercialized phantoms are made to survey imaging system since this is essential increase diagnostic accuracy for quality assurance. In contrast, few customized specifically represent multi-compartment models. because complicated calculations as defined solve time-consuming verifications obtained solutions impeded...

Metastatic pulmonary calcification (MPC) characterized by diffuse calcium deposition in the lungs is known to occur patients with chronic renal failure. However, MPC artery uncommon and has only been detected a few severe disorders. A 48-year-old man failure had cough progressive dyspnea. Ventilation-perfusion (V/Q) lung scans showed multiple large-sized mismatched V/Q defects left middle lower zones of lungs, which was consistent high probability embolism (PE). The findings scintigraphy...

Background: Cobalamin (Cbl) is an essential vitamin for human health. While increasing body of evidence supports the negative impact Cbl deficiency on cognition, causality has yet to be determined, and reported therapeutic responses after supplement therapy have been inconsistent. Besides, few reports described neuroimaging characteristics associated with response. Methods: To describe compare technetium-99m ethyl cysteinate dimer single-photon emission computed tomography (Tc-99m-ECD SPECT)...

Thyroid nodules (TNs) are pathological changes characterized by abnormal proliferation of thyroid gland tissue. Approximately 19% to 67% asymptomatic individuals diagnosed with TNs, the majority being benign and 4% 6.5% cancer nodules. Western medicine recommends regular examinations surgery, while traditional Chinese (TCM) provides an alternative choice maintain function reduce need for surgery. However, in Taiwan, research on TCM treatment TNs is primarily limited case reports, lacking...

The advanced technique comprising an enhanced multi-W-shaped gauge and Taguchi-based analytical program of gamma camera (GC) spatial resolution optimization was proposed successfully applied to the routine diagnosis nuclear examination. indigenous revised from a V-shaped for computer tomography (CT) scanning. slit had gradually narrowing gap between two adjacent V-slits; once beyond GC recognizable limit, acquired imaging blurred, discrimination V-slits lost. five factors data collecting...

This study introduces a comprehensive benchmark designed to evaluate the performance of large language models (LLMs) in understanding and processing cultural knowledge, with specific focus on Hakka culture as case study. Leveraging Bloom's Taxonomy, develops multi-dimensional framework that systematically assesses LLMs across six cognitive domains: Remembering, Understanding, Applying, Analyzing, Evaluating, Creating. extends beyond traditional single-dimensional evaluations by providing...

When using F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET) in the detection of various malignant tumors, those with normal or low metabolic activity may lead to false-negative results. In combination computed (CT) and anatomic concepts, we successfully identified a patient renal cell carcinoma, which showed uptake on an PET/CT imaging at upper pole right kidney.

A 77-year-old man with lung cancer underwent fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). Cervical FDG uptake of variable intensity was detected corresponding to enlarged masses in the bilateral parotid and left submandibular regions. We suspected metastases from primary or coexisting salivary gland neoplasms. Histopathological examination FDG-avid mass revealed Mikulicz disease, an uncommon autoimmune disease involving glands. present this case...
