“…Our results revealed that about (75%) of our patients show bone metastasis, (50%) show lung metastasis, (40%) show liver metastasis and about (5%) show special sites of metastasis as adrenal gland, ovaries, brain, chest wall and abdominal wall. This was agreed by Grant R Williams, et al, [17] . Who reported that bone, lung and liver were most common sites for metastatic deposits respectively.…”

Background: The diagnosis of breast cancer requires sensitive and specific examinations to detect the lesion and avoid surgical intervention in benign lesions. Moreover, therapeutic planning requires accurate preoperative evaluation of tumor extent and detection of multicentric and multifocal lesions. Aim of Study:This study aimed to assess the diagnostic accuracy of CT and Isotope scan in detection of breast cancer and their metastatic lesions.Patients and Methods: This study included 38 female patients who were referred from Oncology Center of Mansoura University and Outpatient Surgery Clinic based on physical finding of palpable breast masses. All patients underwent clinical history and examination, Ultrasound and mammography, Contrast enhanced CT, Isotope scan and SPECT / CT fusion technique if available.Results: Contrast enhanced CT, mammography, and US are 100% specific for diagnosis of malignant mass but they differ in their sensitivity that was 88% for mammography, 97% for US and 100% for post-contrast CT. Comparison of the area under the ROC curve of the perfect post-contrast CT versus the two other modalities revealed that the difference was statistically significant when comparing it with mammography (p=0.0351) but it was not statistically significant when comparing it with US (p=0.2787).Conclusions: CT mammography proved high efficacy in detection of solitary primary and bilateral masses. It has the advantage of wide images scope to detect LNs as well as other skin and chest wall lesions. We indicated in our study to do bone scan and whole body CT for all patients of breast cancer as combination between them which proved highly sensitivity and specificity in detection of primary breast masses as well as metastatic lesions.

Purpose: The purpose of this study is to automate the slice thickness verification on the AAPM CT performance phantom and validate it for variations of slice thickness, position from iso-center, and reconstruction filter.Methods: An automatic procedure for slice thickness verification on AAPM CT performance phantom was developed using MATLAB R2015b. The stair object image within the phantom was segmented, and the middle stair object was located. Its angle was determined using the Hough transformation, and the image was rotated accordingly. The profile through this object was obtained, and its full-width of half maximum (FWHM) was automatically measured. The FWHM indicated the slice thickness of the image. The automated procedure was applied with variations in three independent parameters, i.e., the slice thickness, the distance from the phantom to the iso-center, and the reconstruction filter. The automated results were compared to manual measurements made using electronic calipers.Results: The differences of the automated results from the nominal slice thicknesses were within 1.0 mm. The automated results are comparable to those from manual approach (i.e., the difference of both is within 12%). The automatic procedure accurately obtained slice thickness even when the phantom was moved from the iso-center position by up to 4 cm above and 4 cm below the iso-center. The automated results were similar (to within 0.1 mm) for various reconstruction filters. Conclusions:We successfully developed an automated procedure of slice thickness verification and confirmed that the automated procedure provided accurate results.It provided an easy and effective method of determining slice thickness.
