OBJECTIVE To compare the efficacy of interstitial laser photocoagulation (ILP) with radioiodine in hot thyroid nodules. DESIGN Thirty consecutive outpatients with subclinical or mild hyperthyroidism and a scintigraphically solitary hot nodule with extraglandular suppression were randomized to either one ILP session or one radioiodine ((131)I) dose.

BACKGROUND The aim was to determine the reliability and reproducibility of sentinel node biopsy (SNB) as a staging tool in head and neck squamous cell carcinoma (HNSCC) for T1/2 clinically N0 patients by means of a standardized technique. METHODS Between June 1998 and June 2002, 227 SNB procedures have been performed in HNSCC cases at six centers. One(More)
PURPOSE To compare sentinel lymph node biopsy, magnetic resonance imaging (MRI), Doppler ultrasonography, and palpation as staging tools in patients with T1/T2 N0 cancer of the oral cavity. MATERIAL AND METHODS Forty consecutive patients were enrolled (17 F and 23 M, aged 32-90 years), 24 T1 and 16 T2 cN0 squamous cell carcinoma of the oral cavity.(More)
BACKGROUND Radioiodine (131I) therapy is widely used for treatment of non-toxic goiters. A limitation for this treatment is a low thyroid radioiodine uptake (RAIU), often encountered in these patients. AIM To estimate the impact of various factors on the thyroid RAIU. METHODS We examined prospectively 170 patients (146 females; age range: 22-87 yrs)(More)
BACKGROUND Use of recombinant human thyrotropin increases the thyroid radioiodine (iodine 131 [(131)I]) uptake and may have a role in the context of (131)I therapy of benign goiter. METHODS In a double-blind, placebo-controlled trial, 57 patients with nodular nontoxic goiter (51 women and 6 men) were randomized to receive either 0.3 mg of recombinant(More)
BACKGROUND Recombinant human TSH (rhTSH) can be used to enhance (131)I therapy for shrinkage of multinodular goiter (MG). OBJECTIVE, DESIGN, AND SETTING The objective of the study was to compare the efficacy and safety of 0.01 and 0.03 mg modified-release (MR) rhTSH as an adjuvant to (131)I therapy, vs. (131)I alone, in a randomized, placebo-controlled,(More)
Structural imaging with computed tomography (CT) and MR imaging is the mainstay in primary diagnosis of primary brain tumors, but these modalities depend on morphologic appearance and an intact blood-brain barrier, and important aspects of tumor biology are not addressed. Such issues may be alleviated by (18)F-fluorodeoxyglucose (FDG)-PET and FDG-PET/CT(More)
Attenuation correction may improve the diagnostic accuracy of myocardial perfusion imaging (MPI). However, few studies have dealt with the clinical consequences for reporting. We compared routine reports based on scatter-corrected MPI (MPI-routine) with consensus readings of scatter-corrected (MPI-scatter) and scatter plus attenuation-corrected studies(More)
The techniques of dual-time-point imaging (DTPI) and delayed-time-point imaging, which are mostly being used for distinction between inflammatory and malignant diseases, has increased the specificity of fluorodeoxyglucose (FDG)-PET for diagnosis and prognosis of certain diseases. A gradually increasing trend of FDG uptake over time has been shown in(More)
PURPOSE To validate lymphatic mapping combined with sentinel lymph node biopsy as a staging procedure, and to evaluate the possible clinical implications of added oblique lymphoscintigraphy and/or tomography and test the intra- and interobserver reproducibility of lymphoscintigraphy. MATERIAL AND METHODS Forty patients (17 F and 23 M, aged 32-90) with 24(More)
