Amide proton transfer (APT) imaging is a technique that reflects the level of amide proton transport of hydrogen ions in water to peptides and proteins within the tumour by using magnetic resonance imaging without contrast administration. This technique can more accurately reflect the protein level, pH value, and other relevant information within the tumour. Currently, APT is widely used in glioma research. In this paper, Read More

Background: Cone Beam Computed Tomography (CBCT) represents the optimal imaging solution for the evaluation of the maxillofacial and dental area when quantitative geometric and volumetric accuracy is necessary (e.g., in implantology and orthodontics). Moreover, in recent years, this technique has given excellent results for the imaging of lower and upper extremities. Therefore, significant interest has been increased i Read More

Objective: The objective of the paper was to compare the value of CT and MRI in the diagnosis of primary carcinoma of the liver. Methods: A retrospective analysis was performed on 132 cases of suspected primary liver carcinoma. CT and MRI diagnosis were performed and pathological results were compared to determine the diagnostic value of the two methods. Results: 96 cases were diagnosed as primary liver carcino Read More

Purpose: The aim of the study was to investigate the feasibility of discriminating between clear-cell renal cell carcinoma (ccRCC) and non-clear-cell renal cell carcinoma (non-ccRCC) via radiomics models and nomogram. Methods: The retrospective study included 147 patients (ccRCC=100, non-ccRCC=47) who underwent enhanced CT before surgery. CT images of the corticomedullary phase (CMP) were collected and features fr Read More

Aims: The aim of the study is to demonstrate a non-invasive alternative method to aid the decision making process in the management of adrenal masses. Background: Lipid-poor adenomas constitute 30% of all adrenal adenomas. When discovered incidentally, additional dynamic adrenal examinations are required to differentiate them from an adrenal malignancy or pheochromocytoma. Objective: In this retrospective stu Read More

Background: Delphian lymph node (DLN) has been considered to be a gate that predicts widespread lymph node involvement, higher recurrence and mortality rates of head and neck cancer. Objective: This study aimed to establish a preoperative ultrasonography integrated machine learning prediction model to predict Delphian lymph node metastasis (DLNM) in patients with diagnosed papillary thyroid carcinoma (PTC). Metho Read More

Background: Parkinsonism is a term used for the collection of clinical features that cause movement disorders similar to those in Parkinson’s disease. Accurate differentiation of these disorders is critical for the treatment and prognosis of any disease. Fluorine-18 N-(3-fluoropropyl)-2β- carboxymethoxy-3β-(4-iodophenyl) nortropane (F-18 FP-CIT) has been used in the evaluation of parkinsonism by its uptake in the dopam Read More

Objective: We assessed the feasibility of spectral CT imaging for diagnosing lung adenocarcinomas manifesting as ground-glass nodules (GGNs) with varying Ki-67 expression. Methods: Spectral CT parameters in 116 patients with lung adenocarcinomas manifesting as GGNs were analyzed. Cases were grouped into pre-invasive/minimally invasive adenocarcinoma (pre/MIA) and invasive adenocarcinoma (IA) groups. The Ki-6 Read More

Objective: The present study aimed to improve the diagnosis and treatment outcome of cerebrospinal fluid (CSF) rhinorrhea caused by patent meningoencephalocele of Sternberg’s canal of the sphenoid sinus by analyzing the clinical data and imaging features of two rare cases of this disease and by reviewing the relevant literature for possible etiology, diagnoses, and treatments. Methods: Together with the relevant lit Read More

Background: Spinal radiographic analyses are valid and reliable practices used for patient management in healthcare. Technologies and tools used for these analyses need to be valid and reliable. Objective: This study investigates repeated accuracy for validity and intra- and inter-examiner reliability of computer-aided lateral spinal radiograph measurements using PostureRay® EMR software. Methods: Rectangle renderings Read More

Background: Haglund’s syndrome is a common cause of heel pain but often neglected clinically. Haglund’s syndrome refers to a series of symptoms caused by impingement among posterosuperior prominence of the calcaneus, bursa and Achilles tendon. It is difficult to distinguish Haglund’s syndrome from other causes of heel pain by clinical diagnosis. Imageology is of great value in the diagnosis of Haglund’s synd Read More

Background: Diffusion tensor imaging (DTI), a novel method of describing nerve structure, is a special form of magnetic resonance imaging (MRI). This new imaging method can be used to locate the diseased nerve roots in lumbar disc herniation. Objective: The objective of this study is to compare patient outcomes between single-level and doublesection percutaneous endoscopic lumbar discectomy (PELD) in the treatmen Read More

Background: In abdominal magnetic resonance imaging (MRI), the late hepatic arterial phase is particularly important for the diagnosis of hepatocellular carcinoma (HCC). However, poor patient compliance with breath-hold imaging acquisition protocols and the administration of the liverspecific contrast agent gadolinium ethoxybenzyl-diethylenetriaminepentaacetic acid (Gd-EOB-DTPA) increases the motion artifacts t Read More

Background: In patients treated with curative surgery for colorectal cancer, the single-phase (portal phase) abdomen-pelvic computed tomography (CT) follow-up is routinely performed to detect any recurrent lesions. Objective: The objective of this study is to evaluate CT features implying metastasis in newly appearing hepatic lesions on single-phase CT after colorectal cancer surgery. Methods: Of 1,227 patients who under Read More
