BACKGROUND AND PURPOSE If magnetic resonance imaging (MRI) is to compete with computed tomography for evaluation of patients with acute ischemic stroke, there is a need for further improvements in acquisition speed. METHODS Inclusion criteria for this prospective, single institutional study were symptoms of acute ischemic stroke within 24 hours onset,(More)
Multidetector CT has become widely available and with it the ability to rapidly create detailed reformatted images. Multiplanar images can be created depicting the anatomy in planes other than the traditional axial plane, using isotropic to near-isotropic data. It is important for both clinicians and radiologists to be aware of this capability in order to(More)
PURPOSE The study aims to assess the tolerance of elderly patients (70 years or older) with locally advanced rectal cancers to image-guided radiotherapy (IGRT). A retrospective review of 13 elderly patients with locally advanced rectal cancer who underwent preoperative chemoradiation using IGRT was performed. Grade 3-4 acute toxicities, survival, and(More)
OBJECTIVE Cutaneous neuroendocrine lesions of the external auditory canal (EAC) are exceptionally rare, with only five cases reported in the literature. In this case report, we present a patient with a recurrent carcinoid tumor in the EAC, which has yet to be described. PATIENTS A 38-year-old woman presenting with otalgia, aural fullness, and decreased(More)
BACKGROUND Chordoma is a rare invasive bone tumor that may occur anywhere along the neuraxis. A total of three primary histological varieties have been identified: conventional, chondroid, and dedifferentiated. CASE PRESENTATION We report a case of an 8-year-old white girl who presented with conventional chordoma, was treated with surgical resection and(More)
Breast, lung, and prostate cancers are the three most common malignancies to metastasize to the temporal bone. Still, metastatic prostate cancer of the temporal bone is a rare finding, with approximately 21 cases reported in the literature and only 2 cases discovered more than 10 years after initial treatment of the primary. This disease may be asymptomatic(More)
A cute ischemic stroke (AIS) is a common and often devastating disorder; however, acute treatments that reduce long-term disability are available if patients present within the timewindow for treatment. Neuroimaging plays a critical role in the evaluation of these patients. Multimodal computed tomography (CT) or magnetic resonance imaging (MRI) has been(More)

Magnetic resonance spectroscopy (MRS) is a non-invasive technique to detect metabolites within the normal and tumoral tissues. The ability of MRS to diagnose areas of high metabolic activity linked to tumor cell proliferation is particularly useful for radiotherapy treatment planning because of better gross tumor volume (GTV) delineation. The GTV may be(More)
Objectives To describe the work-up and surgical management of an osteoblastoma involving the lateral skull base. Typically occurring in the spine or long bones, osteoblastomas of the craniofacial skeleton are exceedingly rare and infrequently reported. A review of the current literature regarding temporal bone osteoblastoma, diagnosis, and treatment is(More)
