BACKGROUND: Although PET has been shown to be highly sensitive in the primary staging of lymphoma, previous studies with small numbers of patients indicated that low-grade NHL may not always be adequately detected by PET. We undertook this study to determine factors influencing the detection of lesions by PET in low-grade NHL and to evaluate the utility of PET in this indication. PATIENTS AND METHODS: Forty-two patients underwent conventional staging procedures (clinical examination, oto-rhino-laryngologic examination, computed tomography of the chest, abdomen and pelvis, gastroscopy and bone marrow biopsy as well as whole-body non-attenuation corrected 18F-FDG-PET RESULTS: PET detected 40% more abnormal lymph node areas than conventional staging in follicular lymphoma but was inappropriate for the staging of small lymphocytic lymphoma where it detected less than 58% of abnormal lymph node areas. PET showed more lesions than conventional staging for peripheral (34% more lymph node areas detected) and thoracic lymph node (39% more) areas but not for abdominal or pelvic lymph nodes (26% fewer areas detected). The sensitivity to detect bone marrow infiltration was unacceptably low for PET. In contrast, PET was as effective as standard procedures for the detection of other extranodal localizations, although a few localizations were detected only by PET and a few others only by conventional procedures. CONCLUSIONS: PET may contribute to the management of patients with low-grade follicular NHL. For the other low-grade lymphoma subtypes, the role of PET is less evident. Further studies using PET to evaluate the results of treatment or to diagnose disease recurrence are warranted in low-grade follicular NHL. [less ▲]

PURPOSE OF REVIEW: To review the current role and the limitations of F-fluorodeoxygenase positron emission tomography in the management of lymphoma, with a particular focus on studies published since January 2004. RECENT FINDINGS: F-fluorodeoxygenase positron emission tomography should be routinely performed at the initial diagnosis of patients with suffering from Hodgkin's disease because it adds useful informations to conventional staging techniques. Residual F-fluorodeoxygenase uptake is an important prognostic factor after one or a few cycles of chemotherapy, but it is clearly too early to change patient treatment on the basis of F-fluorodeoxygenase positron emission tomography results. F-fluorodeoxygenase positron emission tomography is the best noninvasive imaging technique after treatment; however, it is always indicated to correlate positron emission tomography findings with clinical data, other imaging modalities, a biopsy, or all three to reduce the risk of false positive results. There are some concerns about the positive predictive value of positron emission tomography after treatment, especially in childhood lymphoma. Clinicians should be aware of positron emission tomography findings in specific clinical conditions in this patient population. F-fluorodeoxygenase positron emission tomography combined with computed tomography offers advantages over the two used separately and read side by side. It may be particularly useful for the planning of radiation therapy or for the planning of a surgical biopsy. Several studies have shown that F-fluorodeoxygenase positron emission tomography is definitively superior to Ga scintigraphy. New radiotracers such as F-fluorothymidine may be useful for the noninvasive assessment of proliferation in vivo. SUMMARY: F-fluorodeoxygenase positron emission tomography has become the most important nuclear medicine imaging modality in the field of lymphoma. It should be routinely used in the treatment of lymphoma patients. [less ▲]

Positron emission tomography (PET) allows studies of cerebral metabolism and blood flow and has been widely used to investigate physiological mechanisms underlying altered states of consciousness. The aim of this chapter is to review the current literature on brain metabolism during physiological or pathological loss of consciousness including studies on disorders of consciousness arising from severe brain injury (vegetative/unresponsive or minimally conscious states), and related non-pathological conditions such as sleep and hypnotic states. Identifying brain areas specifically involved in conscious processing, these studies have contributed to our understanding of the underlying physiology of consciousness. The precuneal and cingulate cortices, for example, seem to be key areas for maintaining consciousness awareness. Other areas such as hypothalamus, amygdala or the temporo-occipital cortex seem to play a role in different states of unconsciousness such as rapid eye movement sleep and hypnosis. PET studies permit a better comprehension of the loss of consciousness, and focus the implication of specific neural areas and networks in pathologically (vegetative/unresponsive or minimally conscious states), physiologically (sleep), and hypnotically altered states of consciousness.

Positron emission tomography demonstrates different abnormalities of cerebral metabolism or characteristic disturbances of neurotransmission systems in "cortical" and "subcortical" dementias. Those patterns may reflect the underlying anatomopathology, but may also give clues to the pathophysiology of a disease and its symptoms. [less ▲]

Advances in imaging techniques have allowed more precise staging and better evaluation of the effect of new treatment modalities. The limitations of conventional morphologic imaging techniques are well known. Positron emission tomography (PET) using fluorine-18-labeled fluorodeoxyglucose is now routinely used for initial staging and re-evaluation during or after treatment of Hodgkin's disease and aggressive non-Hodgkin's lymphoma (NHL), but not in low-grade NHL. In the first part of this review, the relationship between glucose metabolism as measured by PET, pathological findings including histological grade and proliferative activity, and prognosis are analyzed. In the second part, the potential role of PET in the staging and follow-up of low-grade NHL is discussed. Published data indicate that PET may contribute to the management of low-grade follicular NHL. [less ▲]

BACKGROUND: Cyst infection remains a challenging issue in patients with autosomal dominant polycystic kidney disease (ADPKD). In most patients, conventional imaging techniques are inconclusive. Isolated observations suggest that (18)fluorodeoxyglucose ((1)(8)FDG) positron-emission computed tomography (PET/CT) might help detect cyst infection in ADPKD patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Comparative assessment of administrative databases from January 2005 to December 2009 identified 27 PET/CT scans performed in 24 ADPKD patients for suspicion of abdominal infection. Cyst infection was definite if confirmed by cyst fluid analysis. Cyst infection was probable if all four of the following criteria were met: temperature of >38 degrees C for >3 days, loin or liver tenderness, C-reactive protein plasma level of >5 mg/dl, and no CT evidence for intracystic bleeding. Episodes with only two or three criteria were grouped as "fever of unknown origin". RESULTS: Thirteen infectious events in 11 patients met all criteria for kidney (n = 3) or liver (n = 10) cyst infection. CT was contributive in only one patient, whereas PET/CT proved cyst infection in 11 patients (84.6%). In addition, 14 episodes of "fever of unknown origin" in 13 patients were recorded. PET/CT identified the source of infection in nine patients (64.3%), including 2 renal cyst infections. Conversely, PET/CT showed no abnormal (1)(8)FDG uptake in 5 patients, including 2 intracystic bleeding. The median delay between the onset of symptoms and PET/CT procedure was 9 days. CONCLUSIONS: This retrospective series underscores the usefulness of PET/CT to confirm and locate cyst infection and identify alternative sources of abdominal infection in ADPKD patients. [less ▲]

Drawing on whiteness studies and psychoanalytical theory, this article explores representations of interracial relationships as a means to claim and/or contest the ideal of whiteness in Mohsin Hamid’s The Reluctant Fundamentalist. In Hamid’s novel, the 9/11 attacks trigger a crisis in self-identification for model-minority Pakistani protagonist Changez, which proves illuminating in terms of the invisible racial subjugation exerted so far upon him by Jim, Changez’s passport into the corporate world, and by Erica, his (white) lifeline to exclusive Manhattan. The article focuses on the ways in which Hamid uses the post 9/11 context to reveal the racial melancholia surreptitiously informing today’s “new” versions of the American Dream, which is apparent in Changez’s and Erica’s relationship as well as in their parallel impossible mourning of the broken mirror of “white” Am/Erica. Emphasizing the extent to which whiteness and racial melancholia permeate the discourse of assimilation, Hamid’s book rewrites the “new” American Dream as what Anne Anlin Cheng has called a “fantasy built on absences”.

Towards the end of the 20th century, as the propagation of new discourses of ethnic success generated new versions of the American Dream, “America” came to signify not only immigrant mobility and whiteness, but also multiculturalism. As Inderpal Grewal argues in Transnational America, this paradox of sorts was only made possible through a slippage in the meaning of “white,” within which whiteness still connoted Anglo-America, yet extended its meaning to include a more heterogeneous group that passed as white through the endorsement of culturally-specific consumerist practices and middle-class norms of behaviour. Posing as multicultural yet covertly fastening whiteness to an ideal Americanness, these so-called “new” versions of the American Dream elevated the Asian American community to “model minority” status, thus contributing to rationalize away the lure that a “relative whiteness” could somehow be acquired by non-white minority groups. Drawing on whiteness studies and psychoanalytical theory, my paper will explore representations of interracial relationships as a means to claim and/or contest the ideal of whiteness in Mohsin Hamid’s The Reluctant Fundamentalist. In Hamid’s novel, the 9/11 attacks trigger a crisis in self-identification for model-minority protagonist Changez, which proves illuminating in terms of the invisible racial subjugation exerted so far onto him by Jim, Changez’s passport into the corporate world, and by Erica, his (white) lifeline to exclusive Manhattan.

Emphasizing the extent to which whiteness and racial melancholia permeate the discourse of assimilation, Hamid’s book rewrites the “new” American Dream as a “fantasy built on absences” (Anne Anlin Cheng).
