PURPOSE This study was performed to evaluate the changes of jaw bone density around the dental implant after placement using computed tomography scan (CT-Scan). MATERIALS AND METHODS This retrospective study consisted of 30 patients who had lost 1 posterior tooth in maxilla or mandible and installed dental implant. The patients took CT-Scan before and after implant placement. Hounsfield Unit ...

While CT imaging is excellent for demonstrating bone structures, it is unable to display an accurate rendition of the teeth. To address this problem, a method of incorporating accurate teeth into the CT scan was developed. This method combined a 3D CT bone model with digital dental models creating a “precise skull model”. An experiment was completed to test the accuracy with which the digital d...

chronic rhinosinusitis (crs) is a common disease which is usually diagnosed clinically, considering the combination of natural history, physical examination and imaging studies. this study aimed to evaluate the clinical value of routine postoperative histopathologic examination (pohe) in patients with a clinical diagnosis of chronic rhinosinusitis with polyposis (crswp), or without polyposis (c...

in this study, 22 patients (15-75 years old) were selected and transferred to ct scan for tumor ablation. for ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. then, laser probe inserted through the needle and laser energy delivered. although we ...

PURPOSE Chronic hand and wrist pain is a common clinical issue for orthopaedic surgeons and rheumatologists. The purpose of this study was 1. To analyze the interobserver agreement of SPECT/CT, MRI, CT, bone scan and plain radiographs in patients with non-specific pain of the hand and wrist, and 2. to assess the diagnostic accuracy of these imaging methods in this selected patient population. ...

Figure 1. Top, An abdominal CT scan with contrast enhancement demonstrates a liver abscess at the lateral segment of the left hepatic lobe, with a linear fish bone (arrow) visible within the abscess. Bottom, A non–contrast-enhanced CT scan in oblique coronal reformation demonstrated that the fish bone was retained in the liver without any sequelae. prolonged courses of oral artesunate to our pa...

Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...

However, a single view of orthopantomogram (panorex) is useful for both mandible and maxilla  Chest x-rays  Computerized tomographic scan is mainly useful for bone lesions as in osteomyelitis giving reduced CT no. in areas of bone destruction and close to normal CT no. in areas of bone formation. Fluids, abscesses and exudates gives varying opacities and lucencies with CT no. more than that o...

Langerhans cell histiocytosis (LCH) is a benign disorder related to the histiocytes which can infiltrate bone tissue. The most effective method for demonstrating severity of this disease is PET/CT and bone scintigraphy might show bone lesions. We present a seventeen year old male patient with disseminated LCH presented with exophtalmos and having multiple vertebral lesions which were identified...

Introduction: Accurate staging plays an important role in management of patients with prostate cancer especially in high-risk group. Today, [68Ga]Ga-PSMA-11 PET/CT should be considered as the preferred imaging tool for treatment planning and initial staging of the disease. Methods: A total number of 628 patients with prostate cancer referred to...
