1. The impact of multimodality integrated positron emission tomography-computed tomography on improving the staging and management of head and neck malignancy: a cross- sectional study
ABSTRACT BACKGROUND: Clinical assessment of head and neck cancers is highly challenging owing to the complexity of regional anatomy and wide range of lesions. The diagnostic evaluation includes detailed physical examination, biopsy and imaging modalities for disease extent and staging. Appropriate imaging is done to enable determination of precise tumor ext

2. Diagnostic Performance of Digital Radiograph and Low-Dose Computed Tomography for the Diagnosis of Fishbone Retention in the Oropharynx
Abstract Introduction Fishbone foreign body retention is one of the most common problem with various clinical manifestations from asymptomatic, abscess formation, and perforation to mediastinitis with subsequence morbidity and mortality. Accurately identifying the location of the fishbone leads to precise removal, which, in turn, prevents serious consequenc

3. Relationship of the anterior ethmoid sinus to the lacrimal sac: a computed tomography study
Abstract Objective: To analyze the anatomical relationship between the lacrimal sac and the agger nasi cell on Computed Tomography (CT); to correlate the right and left sides on each scan. Methods: CT scans of adult patients were reviewed for pneumatization of the agger nasi and its relationship to the lacrimal sac. The degree of agreement between the righ

4. Computed-tomography based scoring system predicts outcome for clinical lymph node-positive patients undergoing radical cystectomy
ABSTRACT Purpose: Contrast-enhanced CT scan is the standard staging modality for patients with bladder cancer undergoing radical cystectomy (RC). Involvement of lymph nodes (LN) determines prognosis of patients with bladder cancer. The detection of LN metastasis by CT scan is still insufficient. Therefore, we investigated various CT scan characteristics to

5. Deep learning model-assisted detection of kidney stones on computed tomography
ABSTRACT Introduction: The aim of this study was to investigate the success of a deep learning model in detecting kidney stones in different planes according to stone size on unenhanced computed tomography (CT) images. Materials and Methods: This retrospective study included 455 patients who underwent CT scanning for kidney stones between January 2016 and

6. Surgical Removal of The Mechanical Valve Leaflet Dislocated into The Pulmonary Vein
ABSTRACT Accidental detachment of mechanical valve leaflet during implantation is a rare and potentially serious complication. When the lost leaflet cannot be found by direct visualisation, additional diagnostic procedures are necessary to detect it. Computer tomography is the best detection method, but the patient needs reoperation. We presented a patient i

7. The Value of Spiral Chest Computed Tomography Scan in the Diagnosis of Asymptomatic Coronavirus Carriers among Paranasal Sinus and Pharynx Surgery Candidates
Abstract Introduction The nasopharynx and oropharynx are the main colonization sites of coronavirus. Therefore, patients with paranasal sinuses and pharyngeal problems (ear, nose, and throat [ENT] patients) predispose coronavirus infection. Ear, nose, and throat patients with concomitant asymptomatic coronavirus infection may develop severe pneumonia follow

8. Performance of 68Ga-labeled prostate-specific membrane antigen ligand positron emission tomography/computed tomography in the diagnosis of primary prostate cancer: a systematic review and meta-analysis
ABSTRACT Objective: To explore the feasibility of 68Ga-PSMA PET/CT in diagnosing primary prostate cancer. Materials and Methods: Embase, PubMed and Cochrane Library databases were searched for studies published before July 2020. The studies that used 68Ga-PSMA PET/CT for detecting primary prostate cancer, and pathological biopsy as the reference standard w

9. A clinical trial on 3D CT scan and polysomnographyc changes after rapid maxillary expansion in children with snoring
Abstract Objective: The present prospective clinical study aimed to investigate the effects of rapid maxillary expansion on the airway, correlating airway volumes obtained on multi-slice computed tomography and polysomnography assessment of oxygen saturation and apnea/hypopnea index. Methods: Twenty-four patients (11 with obstructive sleep apnea and 13 wit

10. Correlation between PET-CT and ct in the staging after the treatment of head and neck squamous cell carcinoma
Abstract Objective: The aim of this study is to find out if a single imaging test is enough to follow-up on an oncological post-treatment patient. In such a case, we would know which was more valuable after comparing the two, by CT or PET-CT. Methods: Between January 2012 and July 2018, we collected data from all patients with previous medical history who

11. Extraparotid Warthin Tumors Imitating Metastasis of Oral Cancers
Abstract Introduction Extraparotid Warthin tumor (WT) is a very rare entity, especially when synchronous with oral cancer (OC). Objective The present study presents a case series of extraparotid WTs detected in the surgical specimen of patients treated for OC. Methods From 2007 to 2016, 336 patients were operated for OC in our institution. Neck dissection

12. Giant Colonic Diverticulitis, an Extremely Rare Presentation of a Rare Disease — Clinical Presentation and Literature Review
ABSTRACT Introduction Giant colonic diverticulum (GCD) is rare phenomenon, with less than 200 cases described in the literature. One of the complications of GCD is diverticulitis. To date, there is paucity of data addressing the diagnosis and management of GCD complicated by acute diverticulitis. Objective To better understand the diagnostic tools, the ini
