In this retrospective monocenter study, we analyzed the outcomes of 130 adult hematological patients who developed a proven (n = 23), probable (n = 71), and possible (n = 36) invasive aspergillosis (IA) in a 13-year period. Forty-nine patients (38%) were recipients of an allogeneic hematopoietic stem cell transplantation (AlloHSCT). The main goal of the(More)
PURPOSE A brachytherapy (BT) boost to the vaginal vault is considered standard treatment for many endometrial or cervical cancers. We aimed to challenge this treatment standard by using stereotactic radiotherapy (SRT) with a linac-based micromultileaf collimator technique. METHODS AND MATERIALS Since January 2002, 16 patients with either endometrial (9)(More)
PURPOSE To assess the role of endorectal magnetic resonance imaging (MRI) in defining local relapse after radical prostatectomy for prostate cancer to help to reassess the clinical target volume (CTV) for adjuvant postprostatectomy radiotherapy. METHODS AND MATERIALS Sixty patients undergoing an endorectal MRI before salvage radiotherapy were selected.(More)
PURPOSE To evaluate the feasibility, tolerability, and preliminary outcomes in patients with prostate cancer treated according to a hypofractionated dose escalation protocol to boost the dominant tumor-bearing region of the prostate. METHODS AND MATERIALS After conventional fractionated external radiotherapy to 64 to 64.4 Gy, 50 patients with(More)
Opportunistic fungal infection is a common cause of serious morbidity and mortality in the immunocompromised host. Combination of pattern recognition with knowledge of the clinical setting is the best approach to pulmonary infectious processes. The aim of this article is to assess the chest radiographs and CT imaging features of different opportunistic(More)
We present a case of aortocaval fistula (ACF) secondary to spontaneous rupture of an atherosclerotic infrarenal aortic aneurysm into the inferior vena cava that was initially diagnosed with computed tomography (CT). This is believed to be the first report of this condition with CT demonstration of the exact site of fistula and CT—pathologic correlation. We(More)
The purpose of this study is to report toxicity and outcome results in patients with gynaecological tumours treated with a final boost using extra-cranial stereotactic radiotherapy (SRT) with a linac-based micro-multileaf collimator technique as an alternative to high-dose rate brachytherapy (HDR-BT). Since January 2002, 26 patients with either endometrial(More)
PURPOSE To assess the potential dosimetric advantages and drawbacks of photon beams (modulated or not), electron beams (EB), and protons as a boost for the tumor bed in deep-seated early-stage breast cancer. MATERIAL AND METHODS Planning CTs of 14 women with deep-seated tumors (i.e., > or =4 cm depth) were selected. The clinical target volume (CTV) was(More)
PURPOSE To assess the usefulness of preoperative coronary computed tomographic (CT) angiography in the detection of coronary artery disease (CAD) in nonselected patients scheduled to undergo noncoronary cardiovascular surgery to avoid unnecessary invasive coronary angiography (ICA). MATERIALS AND METHODS The institutional review board approved the study(More)
Acute chest pain (ACP) is one of the most common presenting symptoms at the emergency department. The differential diagnosis is vast. To exclude life-threatening causes, radiologists encounter an increasing amount of thoracic computed tomography (CT) examinations including CT angiography of the heart and great vessels. The dual- and triple-rule CT(More)
