The aim of this study was to evaluate the usefulness of (99m)Tc-tetrofosmin single-photon emission tomography (SPET) in the detection of both primary breast cancer and axillary lymph node metastasis. We studied 192 consecutive patients in whom primary breast cancer was suspected on the basis of mammography and/or physical examination. After intravenous(More)
AIM Given the few controversial data about the effect of highly active antiretroviral therapy (HAART) on bone mass in HIV patients, we investigated whether a relationship between osteopenia/osteoporosis risk and HAART exists. METHODS In 172 HIV patients, 152 on HAART, 92 including and 60 not including protease inhibitors (PI), 20 naïve and 64 controls, we(More)
UNLABELLED Pinhole SPECT (P-SPECT) has proven to be a high-resolution and sensitive method in both experimental and clinical studies. In this study, we investigated whether P-SPECT combined with conventional planar scintigraphy can give additional information in hyperfunctioning parathyroid gland detection in both primary hyperparathyroidism (pHPT) and(More)
Planar scintimammography (SM) acquired with a conventional gamma camera has proved a useful complementary tool to mammography (Mx) in breast cancer (BC) diagnosis, but with unsatisfactory sensitivity in small size carcinomas. In this study we assessed the role of planar SM with a high-resolution dedicated breast camera (DBC) in BC diagnosis, comparing the(More)
We investigated the clinical impact of breast scintigraphy acquired with a breast specific γ-camera (BSGC) in the diagnosis of breast cancer (BC) and assessed its incremental value over mammography (Mx). A consecutive series of 467 patients underwent BSGC scintigraphy for different indications: suspicious lesions on physical examination and/or on US/MRI(More)
UNLABELLED Ductal carcinoma in situ (DCIS) is a subtype of breast cancer encountered increasingly in clinical practice because of the widespread use of screening mammography. In the present study, we evaluated the usefulness of breast-specific γ-camera (BSGC) scintigraphy in DCIS identification, describing the scintigraphic findings and their correlation(More)
AIM The aim of this study was to compare preoperative planar scintimammography (SM) with high resolution dedicated breast camera (DBC) and conventional mammography in the detection of multifocal, multicentric and bilateral breast cancer and its impact on surgical planning. METHODS A series of 264 consecutive patients, 232 with breast cancer and 32 with(More)
OBJECTIVE Given that few and controversial data have been reported on thyroid function in human immunodeficiency virus (HIV) patients on highly active antiretroviral therapy (HAART), we further investigated whether HAART affects thyroid hormones. DESIGN AND PATIENTS Two hundred two consecutive adult HIV patients in stable clinical condition were enrolled,(More)
AIM The role of leptin in bone metabolism has not yet been fully elucidated and results remain controversial. We investigated whether changes in serum leptin correlated to bone mineral density (BMD) occur in human immunodeficiency virus (HIV) patients on highly active antiretroviral therapy (HAART). METHODS The study population was 117 HIV patients (67(More)
The aim of this study was to evaluate the usefulness of supine 99mTc-tetrofosmin SPECT in the detection of small size breast carcinomas (BC), for which planar scintimammography has showed a low sensitivity. We studied 93 patients with breast lesions </=10 mm, 69 with BC (14 T1a and 55 T1b, 39 palpable and 30 non-palpable) and 24 with benign lesions (16(More)
