Presented herein are systems and methods that provide for improved computer aided display and analysis of nuclear medicine images. In particular, in certain embodiments, the systems and methods described herein provide improvements to several image processing steps used for automated analysis of bone scan images for assessing cancer status of a patient. For example, improved approaches for image segmentation, hotspot detection, automated classification of hotspots as representing metastases, and computation of risk indices such as bone scan index (BSI) values are provided.

Disclosed herein is a fractionated dosing regimen of 131I-labeled 18-(p-iodo-phenyl)octadecyl phosphocholine for the treatment of cancer. The dosing regimen may include a single dosing cycle or multiple dosing cycles. The radiation therapy as described herein may be administered pursuant to a first dosing cycle and a second dosing cycle, with a delay between the two cycles necessitated by a medical reason of the subject.

Provided herein are compounds of Formula (I) or a pharmaceutically acceptable salt thereof. Also provided are compositions including a compound of Formula (I) together with a pharmaceutically acceptable carrier, and methods for imaging prostate cancer cells.

The present invention relates to compounds according to Formula I or Formula II, which are potential bone imaging agents. Certain compounds labeled with .sup.68Ga displayed excellent bone uptake and retention. The present invention also relates to pharmaceutical compositions comprising a pharmaceutical acceptable carrier and a compound of Formula I or Formula II or a pharmaceutically acceptable salt thereof. ##STR00001##

The present invention relates to a pharmaceutical composition comprising a radiohybrid agent containing a silicon-fluoride and a chelating group wherein either the fluorine is .sup.18F or the chelating group contains a chelated radioactive metal, wherein the composition has a pH of 4.0-6.0 and further comprises: 0.1-200 mM citrate buffer; 1-100 mg/mL ethanol; and 5-10 mg/mL sodium chloride.

One aspect of the present invention relates to a method of preparing radiofluorinated substituted alkyl, cycloalkyl, aryl, and alkenyl compounds. In a preferred embodiment, potassium fluoride-18 is used. Another aspect of the invention relates to piperazine compounds containing fluorine-18 that are useful as imaging agents. In certain embodiments, the piperazine compounds contain a quaternary amine. Another aspect of the invention relates to arylphosphonium compounds containing fluorine-18 that are useful as imaging agents. In certain embodiments, the phosphonium compound is a tetraaryl phosphonium salt. Another aspect of the present invention relates to a method of obtaining a positron emission image of a mammal, comprising the steps of administering to a mammal a compound of the invention, and acquiring a positron emission spectrum of the mammal.

The present invention relates to a pharmaceutical composition comprising a radiohybrid agent containing a silicon-fluoride and a chelating group wherein either the fluorine is .sup.18F or the chelating group contains a chelated radioactive metal, wherein the composition has a ph of 4.0-6.0 and further comprises: 0.1-200 mM citrate buffer; 1-100 mg/ml ethanol; and 5-10 mg/ml sodium chloride.
